PS3 won't sell 2 million across November/December, no way, no how. I wish it were otherwise, but PS3 just has the stink of death attached to it, between the dripping disdain on hard core forums like GAF, and the rather complete lack of marketing and high price to the mass market.
Sony can't do much quickly about the first, but they should be able to do something about the second. For all Sony's problems with getting true AAA titles onto the platform (Resistance excluded), they have fallen down most on marketing the thing.
From everything we've been hearing, there'll be a lot of noise about Blu-Ray this holiday season, and a lot of noise about the PS3's price and Blu-Ray movie compatibility and etc. If Sony pushes marketing for Ratchet, Uncharted, Haze, Simpsons, etc., they should get something going, but they have to market the damn thing.
Marketing. Now.
