My quick thoughts:
HD - irrelevant to most Nintendo franchises. Would be nice for Metroid. Otherwise I have a 360.
Gamepad - The lack of true motion gaming is a definite minus in my books. I have yet to see it really adding anything new.
Online - I will believe it when I actually see it. Would be appreciated.
Support - Nintendo fans have said this every generation since GC and been disappointed every time. I don't expect WiiU to be different. For the record, I said it to for Wii (but it was outselling the other two consoles combined at the time).
Games - Yes, I'm sure like GC and Wii before it, WiiU will have some great games. When enough of them come out, I will consider getting a WiiU. Unless the competition has offered something better.
