I was until the last two press conferences. I really like the idea of it, but to be honest it's really lacking in the department that matters most for me: games. Batman and Darksiders i already have, New super mario brothers isn't anything new.
Pikmin is not a launch game,... The only thing that looks interesting is ZombiU but ubisoft has a trackrecord of having launchgames that look amazing in previews, has great marketing but are mostly disappointments when you actually play them.
I fear that when the system finally has interesting games, there will be a new xbox or playstation with better hardware and developers will just stop developing for wiiu like they did with wii.
I hope i am wrong because i love nintendo and really enjoyed the wii (i still do).
