Nothing set in stone as yet, but the clever money is on the launch of the Nokia Lumia 900 at the CES event in January.Invites have gone out for a Nokia event on 9 January 2012 in Las Vegas, with Nokia promising 'the latest news from Nokia' as well as 'stunning demos of Nokia technology in action'. It doesn't mention a new phone launch, but the Lumia 900 is expected in early 2012, with one phone industry employee already confirming that the Windows 7.5 smartphone will be on the shelves at the end of February. Put all the pieces together and it's hard to see Nokia allowing the event to pass off without a glimpse at its new flagship phone. Oh yes, the invite is Windows-themed. That good enough for you?If you've missed the numerous leaked shots and details of the phone previously, you can see an image of the Lumia 900 here, which is said to pack a 4.3-inch ClearBlack AMOLED display (larger than the Lumia 800), as well as a 1.4GHz processor, eight-megapixel camera and the latest Windows Phone Tango operating system.All of which should be confirmed in just a few weeks. You'll be the first to know when it is.
