As far as the original topic goes, I don't think your idea of a SUPER Mario Party adds much more to the series. Nice stuff for sure, but nothign that would move the series forward.
I'ld like some of the old mini games to come back, sure, but I'ld like new mini games more. Also, an online element would be appreciated and I don't know why a Wii U version wouldn't be online enabled. That being said, Mario Party is really a party game, and it would just not be as fun to play online as it is have your buddies next to you. Also, lag might be a concern considering how twitchy a lot of those game are.
