The image is blurry, sure, but you can notice three distinct things even with the blur:
1) The Wii U logo seems to cover the top edge of the bottom plastic to the bottom edge. On the regular Wii U controller, it leaves space on either side of the logo. This could either mean the logo is larger, or there is less plastic at the bottom of the screen.
2) The top plastic above the screen appears thinner, and the blur does not indicate that a camera is present.
3) Everything is brought closer to the screen (look at how close the buttons are, for example), and the screen appears to take up more of the overall controller. This could just be less plastic around the screen though giving the appearance that it's larger, when really it is still the same size simply with less around it giving the illusion that the screen is larger. Of course, the screen could actually be larger too. With the lesser plastic, it really is impossible to tell.
Overall, it does appear to be a different controller which does hint that a cheaper redesign may be on the way. Perhaps they're looking to still try to use the controller, but cut down on the amount of supplies used in order to reduce production costs and drive down the price of the overall system/controller combo. As well, they may just be creating a more accessible replacement for those that want more than one game pad, or for those that "accidentally" or accidentally break theirs. Hell, they could just be making what they see as a more comfortable game pad.
Even then, this may just be an idea that will never see public release, though, it would make you question why they would use anything other than the official controller at any point in the commercial shoot. Even if you say "well I saw a normal Wii U controller at another point", it isn't uncommon for TV commercials to be a myriad of cut together shots, and there's no saying that there wasn't a newer controller design in possession that wasn't meant to be used on that commercial, but accidentally was.
