Where Are The Platforms?

I found a statistic that the average gamer age is 33. So why aren't they developing games that originally got us on consoles in the first place? The Wii will have it's handful of new platforms and with it's downloadable game database of yesteryear the void can be filled. But not with the power of these new systems. The PS3 will have it's Ratchet or Jax but they are played into the ground and i'm not paying $500 or more for a game system. The 360 is already another shooter-box. The game for-cast already shows that. I'm bored.
