Well, it would be nice if Nintendo would release such a console. Because now you really have to have a PS3 or a 360 and a Wii if you want to be able to experience the best games. And, I like being able to have the best graphics at an affordable price.
The mass market might embrace all these Wii series games, but similar games haven't have been embraced like that in earlier eras.
And even though it might be interesting to play Fragile. To me, it's not worth missing out on FFXIII, Bayonetta, MGS4, Gears or Uncharted, and Batman: Arkham Asylum to do so.
