Aside from the playstation fanboys who have brought literally nothing to this conversation, I can understand some of the concerns. For me, the used game market and how these consoles deal with that will be the deal breaker for me. I'm not married to any franchise on any of the three systems. I probably like the Nintendo franchises in Zelda and Metroid the most, and I have no intention of getting the new Nintendo system. Final Fantasy stopped being cool sometime after FFVIII for me when it became so J-Pop it was unplayable.
So there are two things I'll care about - my wallet and the used games since I rarely buy games new (which is directly related to my wallet). We'll see who steps up.
