Marios Karagiannis, the developing superpower behind the title MonsterUp, has published an interesting article on his blog detailing how 2012 is going to be the "Year of Nokia" for Windows Phone. Looking at the above charts, on the left we have the total breakdown of Windows Phone OEMs since early 2011 and on the right we have the representation of the month of January 2012 only (data is extracted from devices playing his games).
There's a clear trend that is noticeable when comparing both charts. Nokia is on the rise (within the Windows Phone market anyway), helped by the quality of the handsets manufactured and the sheer scale of marketing. HTC is still the clear giant, but with the 900 uprising, as well as the probability of the monster Lumia handset being available on a global scale, we should see a further increase to the chunk Nokia owns.
While we have no exact figure for the amount of handsets Nokia has sold, apart from the 1 million shipped estimation by analysts, this is an indicator that the Lumia family is selling. Especially with the 11% jump in Windows Phone OEM shares in just under a month.
