Sorry, have you heard of Gran Turismo 5 and Final Fantasy XIII (Japan). Those are the types of games that are already moving some systems and will move loads afterwards. May I also point out that Gears 2 was not a system seller, it was the massive price cut that made the difference.
I would say there are two type of exclusives in terms of moving consoles:
1. The individual system sellers.
This category probably only includes the Mario games, GT, FF, MGS and Halo. These games alone can make somebody buy a console. The sales due to these games will not just happen at launch, but I bet people bought PS3s the holiday before MGS 4 for MGS 4, if it weren't for MGS 4, they would have got the Xbox that holiday
2. The games that add to these
Games like Uncharted are just added reasons to buy the console. Very very few people would just buy the console for the one game, but for the large number of exclusive titles, or just on top of GT or FF or something like that.
