No, no they aren't. Traditional gaming and the current mobile gaming are completely different experiences. It's like the difference between someone who plays games and a "gamer" (forgive my Scotsman here, it's for an analogy).
While both someone who plays games and a "gamer" might put in a decent amount of hours a week on Angry Birds, Tiny Wings, or whatever the mobile fad of the moment is, the "gamer" is not going to be as satisfied with that. They're going to be drooling over the latest videos for Skyrim, the next Battlefield game, or Deus Ex. A simple mobile game does not scratch that itch. They're completely different experiences, and I've gotten so tired of people equating the two.
It's like saying YouTube is going to overtake movies, because people totally love watching videos of cats. Sure, they spend hours doing that, but no matter how many cute animal videos, vlogs, or LPs they watch, it's never going to serve the same need as a nice big screen movie.

Imagine if kinect-like software were integrated in iOS 6 or 7. Your apps could use it as input. So you make a game that does, then users put the iPad in a stand next to your big screen tv, connect it, and play 'iPad Dance Jam 7' or whatever. I could easily see that happening.
