I would play the game regardless of how it looked, like I'm sure we all would. But to be honest, I would prefer that Capcom try something different for the next game. If they keep doing these NES throwbacks annually, the games will start to stagnate in the public eye. You'll hear the "more of the same" argument come up again, just like what happened with 4-6. Not to mention the retro fad is already starting to die. And that'll cause a slip in sales. True Capcom wouldn't lose much because these games are cheap to make, but a loss is still a loss. That, and the MM7 style is my favorite and I would like to see another game use that.
If they really want to keep doing the 8 bit thing, I'd suggest they not try to push out a new game every year. Take more time and put a lot of effort into the next game. Not to say a lot of effort hasn't been put into 9 and 10, but imagine how much more can be done when the deadline is that much farther away. Advice for a lot of gaming companies, really. *cough*Sonic Team*cough*
