New Super Mario Bros. Wii, Super Mario Galaxy 2, Golden Sun DS, Sin and Punishment 2, and Metroid: Other M.
I'm not embedding them here because that would be a slow-down nightmare. Enjoy!
Hopefully I'll be able to get some footage from Sony later, other Microsoft didn't have much video content available on their press site, so I can't help you guys out there.
Update: Got some screenshots and artwork from the press site. Not posting everything, because of bandwidth limits, etc. But I'm posting stuff that caught my interest.

Not too much, but the stuff is still cool no less. I'm just waiting for Konami to release artwork for Metal Gear Solid: Rising and MGS: Peace Walker so that I can have a real fanboygasm.
