if sony cuts the price again, then yes... and iÄd like to see a 199,- or 249,- PS3 at Christmas, but i think Sony isnt cutting anything this year. (they have enough 'buy it Arguments' right now because of the great Games coming.)
if there is a chance to see a cut next years Christmas Season, together with some 'OMG' Games (like FFvXIII, Killzne 3, LBP3) Sony could have its best year @ 2011. otherwise i have no idea which year could be .
