Yes to the Wii U version. I can envision it. Mario Party 10 exclusive to Wii U. They will bring back the car mode and new minigames created exclusivly for the Wii U's gamepad. The 3DS one...maybe but I am leaning toward no.
For the Mario Party on Wii U, I think they should bring back 10 minigames from each Mario Party, in addition to new minigames! It will be the 10th Mario Party, anyway.
