I do not count Wii myself, I really think that it primarily serves a different market. Sure there is some cross-over.
The future of this gen will be strongly in favor of Sony, is my prediction. X360's best days are now behind it, most of its best exclusives are behind it, Sony exclusives are finally starting to come in respectable numbers and quality.
Starting in 2009 Sony took the lead, not in terms of overall sales but in stable of quality games and finally crossed the chasm to catch up or even surpass MS in some notable genres. 2010 has Mass Effect 2 in MS Stable, vs... metric asston for Sony. ME2 will be something of a big deal, but the year overall will belong to the PS3.
