Wow. This year it only took 22 days into the year for someone to predict the demise of the 360.
Least it's slightly better then the day 1 of 2009 prediction that the PS3 would dominate 09.
On topic: No. The 360 will continue on into at least 2011 as MS primary console. Why would MS be so stupid as to jump consoles when their current one just became profitable.
