Re. console exclusives. No one is saying PS3 doesn't have a fantastic year ahead but to argue that MS won't have any exclusives because they've not announced anything formally yet is a tad naive. As well as Ninja Blade, Halo Wars and a lot of very good Fallout DLC so far this year, there's Tales of Vesperia and Star Ocean IV next month (both of which I'll be getting). There's Splinter Cell: Conviction, Forza 3, APB, Mass Effect 2, Crackdown 2, Huxley, Halo ODST, Lost Planet 2, Alan Wake, it's known Rare and Lionhead both have secret projects in the works and MS set up another new internal studio last year. Ken Levine has hinted about a new project, Mystwalker have been quiet for over a year and I'd imagine MS being MS they've tied up at least another one or two big 3rd party exclusive.
Re. your list. LA Noire has not been confirmed as a PS3 exclusive and Alone in the Dark?
