Are you sure about your examples?

I think you're confusing "xbox live arcade" with "xbox live." You don't have to create games with XNA to get them on xbox live. I specifically remember C++ code in Indie Game: The Movie (for Super Meat Boy). And I'd bet money that Jonathan Blow, the creator of Braid, prefers C++ over C#.

This isn't to say C# isn't a viable option on consoles. I believe FEZ is all C#...that game is incredible, from an art design standpoint at least. It did have visible garbage collection pauses though.

yep, guess ur right, but FEZ and Bastion are definitely made with XNA and in the case of Bastion the Linux/iOS Version uses MonoGame.
