1. I think it will be much better this time around, considering besides classic, there's are the vehicle gimmick for us to try.
2. I think it will have a lot of potential, since it's been a while since Mario Party 8 and Mario Party DS. Even if it still lacks online.
3. The Vehicle Gimmick Mode, not sure, but from the screens, I say it would be very interesting to at least try out.
4. Yes. Classic Mode is a huge part of Mario Party.
5. I think Mario Party 9 will turn out to be a Mario Party game that truly stands out from the rest of the Mario Parties, utilizing the use of motion controls.
