You are right about Halo, but it is Microsoft's only RoK exclusive franchise so far IMO. I.e. if both Microsoft and Sony were to launch a new system with a new iteration of one of their best franchises, Halo is the only weapon in Microsoft's arsenal that would enable them to sell more systems than Sony. Gears of War and Mass Effect are great, but they won't individually beat MGS, God of War, Uncharted or Gran Turismo.
During the previous generation of consoles, exclusives were a huge reason why the PS2 ended up on top I think. Its line-up in 2001 alone was incredible: Gran Turismo 3, GTA 3 , MGS2, Twisted Metal: Black, Devil May Cry, Onimusha Warlords, etc.
