Can I just point out: In your OP you've put a link to a 'GoNintendo' review, but it's just a link to a Gamesweasel video. So it's a Gamesweasel review. I recognised Matt Cuttle's voice as soon as it started :P
Reviews do seem a little mixed so far but it's far too early to call anything. Edge have done their usual, I see. Sometimes I love their reviews because they genuinely make good points; sometimes they're a load of crap. I'll have to wait and see about this one.
One thing I can say is, all the reviews and footage of this game make me want it. Unfortunately, not enough to buy a Wii-U, but when I do get one, this is definitely a title I will be picking up at the same time!
