Not necessarly but of course you could be right. Even on Nintendo games alone it could make it to 60 mil with it's price.

I don't really see how it can happen for the ps3 to not get enough media time. I mean we're talking about Sony here. It's a huge corporation. I find it hard to believe that they won't have enough money to buy enough media time. Not to mention all the advertisements.

What I mean is that the PS3 has got a lot of bad press lately, if that press stays bad and its big exclusives dont review well or even worse get ported to the 360, what happens to its sales?I stick by my lowest possible estimates even though they may seem slightly extreme.
