I've made a lot of fun of fanboy-this and fanboy-that but it's easy to sit on the sidelines and criticise, this is my opinion on the matter:
Kinect
Seriously Microsoft, where are the fucking games? Don't be releasing new hardware peripheral when the only 360-exclusive game I liked from 2009 was Halo ODST (and didn't like it that much) and again this year the only 360-exclusive worth getting seems to be Halo-Reach (again,, not that amazed). And Kinect doesn't look to be changing anything, Dance Central is not that amazing.
Move
Come on Sony, just integrate more Mouse Support. We all know the PS3 has native support for any USB Mouse, it's just no games support it. It's a simple patch to bring it to your back catalogue, if you integrate Move aiming to your back catalogue (of first party) games I'd be interested if you did it for Mouse aim at the same time.
I'm not interested in the 1:1 spatial tracking of Move, only the aiming aspect which (from an inherent desing perspective) it is not as good at as Wii. Mildly interest in rail-shooters on PS3 but Move just doesn't seem to be that good at point-aiming.
MotionPlus
Nintendo wins by default as Zelda: skyward sword is the only real example so far of great use of motion-controls in (likely) a great game. But that is just one game, everything else is using no more than Wii-mote's great pointing ability (Other M) which could just as well if no better be achieved by mouse-aim.
So not surprisingly, Nintendo are delivering "best" as they have been doing this motion-control malarkey for longer. Sony and Microsoft seem to be blind to Wii's best titles (Mario Galaxy, Metroid) and seem to be to be targeting the ULTRA casual and throwing out the baby with the bathwater in terms of game design/art being paramount.
