Hey I read both links...
Carmack didn't actually back up his argument with anything concrete.
The Top Gun game looks very average grapically and tilt/touch controls are not going to win many people over...but the Top Gun name might.
Basically, a lot of hot air at the moment and nothing to get really excited about.
Playing: Borderlands(great co-op,HUGE amount of content),Too Human(better late than never lol),Saints Row 3(Penetrator ftw),Minecraft 360,Harry Potter Lego.
Patiently waiting for: Tomb Raider, Borderlands 2
