The fact the Just Dance still sells millions of copies on an otherwise abandoned system suggests there's still a market for motion controls.
But you can't just duplicate the Wii experience Enhance motion alone wouldn't sell. A new Wiimote would also have to have enough imputs to be able to replace a dual analog to replace the need for a seperate Pro Controller and so all games can be ported easily. That way motion/IR is only used when it enhances and not shoehorned in due to lack of analog/buttons. But that still wouldn't be enough.
WiiU should have been powerful enough to get next gen games without significant loss (this was a mistake with Wii). But that too still isn't enough.
WiiU (like all next gen systems) needs to create a level of gameplay that hasn't been seen before. Otherwise why buy a new console? Since processing power alone no longer accomplishes this (and this is a challenge all next gen systems will face) something else needs to be introduced to take games 'to the next level'. To create that awe factor and get us all to want to go out and buy Mario, Zelda, DK, Mario Kart, Etc., etc., yet again despite it basically being the same game. Wii had motion and online (initially anyway) for that. WiiU's gamepad just fails to inspire. It's just not obvious why this will enhance gameplay.
So what should Nintendo have added (on top of enhanced Wiimote/nunchuk, online, HD, processing power)? I don't know. I don't think anyone here does.
never said that there wasnt a market im just saying that it is not as popular as it once was, hell JD sales have dropped even on WIi, so that tells me people are getting tired. And im not even going to get into the sales of the Wii U version.
We are a long way from having something like the WIimote be able to play ALL the genres to teh point where we dont need a pro controller option. Honestly i donnt think we will ever get there. But i agree with everything else.
