I don't see Sony having any difficulty selling out their stock this holiday season. The reaction from the public has been a overwhelmingly positive one.
There's much you need to learn, young one. So I suggest you go do that because without Steve, Woz and Co. and Xerox, personal computing wouldn't be where it is today if not for those brave few nerds. And MS was totally clueless about the UI and mouse at the time and was totally focused on DOS.
And since you only have two bubbles and can't reply, I win. :P lol
I expect MS to hit back hard at E3 so Sony needs to stay on their toes and also protect their relationship with EA and not allow MS to manipulate BF content like they did with COD. Sony having exclusive DLC with both Bungie and BF would be a boon for the platform since COD and Halo are pretty much played out.
adding more ram won't have the effect that you think that it will. Also MS going to GDDR5 will require a big change to the hardware and also cause a delay(2014 release) and I don't think MS wants to commit the same mistake that Sony did.
