Yeah, it would be great, especially since they seem to be sticking with the idea of not making a sequel or spinoff despite all the promise and untapped potential displayed in Uprising.
I mean the online multiplayer alone would make a decent piece of change if brought to the Wii U eshop with just some of the more visible characters getting cameos. A full blown sequel without the cramp inducing controls due to having due stick support would be stellar with the right push and platform.
