You can't proclaim who takes 2nd place this gen just yet, the 360 has massive amounts of good software and a huge price advantage worldwide. It also has one full year (even more in Eu/Others) more on the market and is as such, closer to its sales peak than the competition.
We'll have a more realistic outlook on things late next year or early 2010 on who's going to take 2nd place in this "war" as I expect both the 360 and the PS3 to have significantly longer lifespans than the x-box had, for instance.
