I just checked again, and I still don't see those games listed in the marketplace. I did come across a banner for each while in the marketplace, but it just brings me to a screen that only has "Game Info" and thats it.
Is there a way to update the marketplace?
Also how are you guys getting to the demos?
Xbox Live tab > Marketplace > Trailers and Demos > niether game is under here.
I also tried all the other sections under the Marketplace but no luck.
