Nintendo would've done better if they skipped the GamePad this generation all together - the system would've come in cheaper and more developers would have developed for the the Wii U.
See that's it right there. I like what the gamepad does, but it could be relegated to an optional accessory. I admire Nintendo's approach of "all or nothing" innovation.
Would I want the next Nintendo system to be just like the Xbox or Playstation? No way. But I hope their next trick is a good one.
