I don't think the PS3 is a lost cause in NA. Its selling just as well as the xbox360 right now. It's only so far behind atm because the xbox360 had a 1 yr head start. You Also need to remember that the original xbox did quite well in NA, so it already had a decent fanbase. Its still too early too call a winner. For all you know, the xbox360 could peak at 15-20mil units in NA.
Also, I think Sony wants to save a bit of money. Advertisements isn't cheap. So they're most likely saving it for the holiday period, where all their big hitters are coming out. I'm sure you're gonna see alot of LBP bundles being advertised.
