360 - 10 million.
Natal will help breath life back into the 360. Price cut is definite for fall 2010, that will help loads, and the must have Exclusive software line up.
PS3 - 15 million.
Japan and EU will be huge for Sony next year due to GT5 and FF13, this is where Sony will really pull away from the 360 in those regions, this is also where Sony will sell most of their PS3's for 2010. The $299 price tag, the RPG lineup, and GOW3 will keep the PS3 competitive in America well into next year.
The motion controller should help a bit, I don't see it or Natal failing because lets face it, motion controllers are here to stay a few buyers will no doubt fall for both MS and Sony's motion controllers. Finally BluRay, it continues to be in demand it will be bigger next year for EU and NA
