Well it seems like motorola is back into their bad habits that almost killed them before the og droid of releasing a ton of small iterative updates in rapid fire mode so I am not expecting anything "big" from them any time soon, who knows what will happen after the google takeover though.
Samsung is pretty clear cut we've got the galaxy s III which if the release is anything like the galaxy s I & II, it will release internationally at the beginning of the summer and make its way stateside next autumn.
HTC has that quad-core ville, that's all I really know about that.
We won't really have a good handle on what next year will be like until CES in january and MWC in march(?),
