Move is DOA.
Kinect is doing well only because it is being heavily advertised. Left to its own devices, it will probably produce Move-like results (ie, shit) within a few months. I'm still convinced at this time that these are just tests to see what works well and what doesn't for the next generation of systems. Uncharted 3 not using Move makes sense because Move was never meant to be a serious alternative to playing games on the PS3. It's just an experimental device. Also, for major releases, first party developers seem to hold back on motion device gaming. Nintendo knew that for Super Mario Galaxy 1 and 2 to be taken seriously, the game had minimal motion control elements. Even the first party developers know that motion gaming is not to be taken seriously when it comes to a serious effort.
Anyway, the PS3 isn't dead but it is a solidly third place console. To drop 25% YOY is pathetic but as the last place console, it really doesn't matter. You know Sony really wants this turd flushed but given the massive amounts of red ink for the system and the huge costs of another system, they're keeping it around to recoup as much of the costs as possible. Sony is trapped in their own prison. I wouldn't consider it a failure but had it been a system without having the name "PlayStation" on it, it never would have got off the ground.
I expect Wii sales to be as insane as they were in December 2009, which sold 3 million that month if I recall. Unless they hit a shortage or something. Xbox 360 will have significant gains over last year and the PS3 will be at 12/09 levels or less.
