Err, I realize this topic was made back in October, but I think it should be pretty obvious as this point that not only will PS3 not be in first for 2011, but will probably be in 3rd. 360 will have the continued strength of Kinect and the dominance of the US market, which is more than offsets the PS3 advantage in Japan. And Wii will continue to sell on the strength of its evergreen titles and Donkey Kong Country, as well as the NSMB bundle. Zelda will also boost its sales during the slow months.
PS3 has a nice looking lineup for next year, but most of those titles are not going to move significant hardware, if even GT5 couldn't.
