What are you people talking about? These look exactly like the ones shown on TGS in September and GDC last month, except they're grey. Just the colour changed, the model is the same (except the already mentioned big thing that plugged the analogue stick in and the round pointer, but that hardly justifies such a reaction).
So what do you mean "proper" ones? I, for one, am hoping grey is a launch colour for the Rev cause to me Nintendo = Grey. NES was grey, SNES was grey, the N64 was black but with grey controller, my GC is the platinum one, so almost grey. And I hope I can choose the grey Rev, as the white one may look good on advertising pictures but I don't want it in my living room. If no grey, then black is next choice.
Of course this is all just opinion, so don't jump me. But I just found it odd that just cause the controller is grey in the pictures the reactions were "I hope it's not the final design", as if the model were completely different.
