I dunno man. It's gonna be hard for a game not run by frostbite or unreal 4 to look good so it'll probably look like a sub standard visual mess of a game. ; --- Well, I suppose it's time to get kidnapped again...
I can see there being more 1v3 style games than in the past. Not necessarily just player count, since 1v4 is now an option, but a lot more focus on games that pit players against each other with different control styles. Also probably more 1 player events that make use of touchscreen / microphone.
That said, I'm anxious to see what kind of boards there are. 9's board play was... different, not necessarily in a bad way, but since it didn't have a 'standard' board, it wasn't really a *true* Mario Party. (Again, that's not necessarily a bad thing. 8 was a true Mario Party and it was all around unpolished)
I'd be really happy if the next game allowed either MP9 or traditional style play on any map; or at the very least a good mixture of map styles.
