MS still has the lead because of head start their of course their doing fine but when ps3 overtakes 360 we will change our argument from "360 still has the lead" to sumthing that favors the 360 just like how the argument went from "haha ps3 getting trashed weekly sales" to "MS sells more software so it doesn't matter" before the ps3 slim launch.
Anyway none of the consoles right now is doomed TBH.
