If a leaked road map on price comparison site Omio, is to be believed, there are a mutlitude of exciting handsets due for release in the second half of this year from all of the major manufacturers. This month, you can supposedly look forward to the release of the Nokia E5-00, the latest messaging orientated device from the Finnish manufacturer that is said to be taking form and function cues from the popular E71 and E72, but creating a more up to date product.

There’s also the Sony Ericsson W20, the return of the iconic Walkman brand. The handset is said to tie together connectivity and multimedia and we can only assume this will include the usual social network integration from the usual suspects; Facebook, Twitter, Flickr et al, that has become the norm on all Smartphones and even feature phones of late.

Samsung are apparently looking to add Android power to their already successful Corby/Genio range with the i550 Europa and enter the market with an affordbale Android blower touting the latest Android OS build, Wi-Fi, GPS and a 2.0 megapixel camera; not a bad spec list for a handset which will no doubt fall into a low cost bracket.

Beginning in August, you can apparently expect to see an 8GB version of the ever-popular Nokia X6, meaning that the power of the X6 will be available at a much lower cost; if your willing to make-do with 8GB of internal storage as oppose to the 16GB currently being offered.

August also sees a new announcement from BlackBerry, the new Curve 9300. Looking to follow the absolute blinding success that has been the 8520 Curve, the new 9300 (rumoured as Kepler) is going to have to be something spectacularly special in order to continue the momentum that has now seen the Blackberry become one of the most popular handsets the world over.

September holds two new colour variants of existing handsets supposedly, namely a pink variant of the Sony Ericsson Vivaz; an already popular HD video touting power-house whilst there’s also a rumoured white version of the previously mentioned Samsung i550 Europa due.

In terms of new handset releases, there’s the Nokia X2; a slender candy bar which looks to follow the success of the X6 with dedicated music buttons, 16GB of internal storage and a 5 megapixel camera. There is also the latest eco-friendly handset from Sony Ericsson, the Hazel which was initially rumoured back in December ’09 and looks to join the Elm and the Cedar as part of the GreenHeart range.

The handset releases for October, are where things really start to get interesting, especially being the build up to that wonderful time of the year that everybody loves so very much. First we have the Sony Ericsson Xperia X8 (Shakira) a handset already covered here at the UK Mobile Phone Blog not long ago. For those that didn’t see it, expect an Android powered handset which fits in between the power-house, flagship Xperia X10 and the tiny X10 Mini; following the Form of the X10 with the function taken from the X10 Mini.

There’s also the Nokia N8, which again, has been covered here on the blog. This is the big one for Nokia, a real make or break handset that will pretty much determine any future success of Nokia as a Smartphone producer. On paper, like so many Nokia’s previous, the N8 looks like a real winner but we’ll wait to get our hands on it before passing judgement.

The HTC Vision, which was covered only a few days ago by us here on the blog also gets a mention for an October release, in essence, the Vision is a QWERTY touting Desire/Nexus One. Enough said. There is also a new handset name leaked, one which we’ve never heard before, the HTC Ace, so keep an eye on the blog as we try to uncover the mystery that is the rumoured Ace; as soon as we know anything, you will too.

The final announcement for October, comes from Sony Ericsson in the way of the Yendo, said to be a full, touch controlled Walkman branded handset that has taken the four-corner functionality found on the X10 Mini, but has left the Google Operating System behind.

Finally, the rumoured announcements from November start with the HTC Gold, apparently pipped to be the first Windows Phone 7 touting handset from the Taiwanese manufacturer. HTC were the manufacturer to really help Android gain traction in the market with the HTC Desire, perhaps they can do the same again for Microsoft’s Windows Phone 7 with the HTC Gold, who knows. Either way, it’ll be a handset to keep an eye on.

The Nokia E7, is said to follow in the footsteps of the N8, with an aluminium chassis and Symbian^3, the really interesting part of this particular annoucement, is that the E7 is also rumoured to include an AMOLED display as well as a full QWERTY keyboard and a tilting touchscreen.

The very last rumour, comes in the form of the Samsung i8700 Cetus, another handset which we know nothing about. However, ‘Cetus’ appears to have conotations and references to star consellations of sea monsters, Aquarius, Pisces and Eradinus. All of which have one theme in common, water; and with ‘Bada’ (the name of Samsungs proprietary OS) meaning Ocean, it’s not a huge leap to make, that the i8700 could be the flagship Bada touting handset from Samsung, joining the already popular Samsung Wave.

Of course, all of the above is purely speculation and rumour, all with the exception of the Nokia N8 and the Sony Ericsson X8. As soon as we hear of any more details or offcial announcements of these handsets we’ll be sure to get it up on the blog.
