I still think there are unique gaming experiences to be had out there, even before VR/holograms/etc. Portal was an amazing game. I think before that game(and I didn't realize it until I played it the first time) I was in a gaming funk. Nothing had wow'd me. Then Portal came along and turned everything on its head. It had a unique villain, physics, story.
So I don't think gaming as we know it is tired and hackneyed. We just have to get gamers to understand when they're being shovel-fed the same game over and over. I for one am sick of first person shooters. They're everywhere.
The one thing iOS will have a hard time doing is immersing the player. It's hard to be really immersed in a game when it's 3x5 and you keep getting text alerts. I'm not at all saying iOS doesn't have some fun games, it's just not the future. I think we try to look at the future of games as what hardware it'll be on, but it really all comes down to a screen and a way to interact with that screen, be it a controller, motion controls, touch, telepathy.
