In the US I think it's another nail in the coffin for the handheld market.
Part of the handheld's appeal here was the "kid gets grounded, stomps into his room and plays DS/Game Boy" ... Wii U can really replace that.
Why play a crappy watered down version of CoD or Lego Batman or whatever ... when you can play the actual console version?
The moment some third party releases a signal enhancer/bouncer for the Wii U wireless signal that extends its range ... it's totally on.
In Japan it may be a game changer also, it is IMO the last, best hope for the console business in Japan, it's a console practically designed for the Japanese lifestyle, where most homes only have one primary TV, that's why a lot of people have migrated to just playing on their handhelds even at home there. Wii U may have a shot at reversing that.
