There is. Mario Party is the normal mode. Bowser Party is the car mode. 

Ouch. That was a little...inappropriate.

That is exactly what I was thinking.

I really hope so. Gives the game a ton more depth. I'd also like to see a possibilty to make caves (entering pipes) and different backgrounds and themes. Looks good regardless, genuinly surprised this game exists.

Mario Party 10 actually looks pretty good as well.

That's what I thought but they went back into the Mario Party mode and they were all together still in a rollercoaster. 

Not really sure what I was looking at.

Also Smash next! As much as I love it I feel a little Smashed out after last night and today

Yeah, a bit surprised by how fun Mario Party 10 looked. They really need to change the dice rolling part though. Make it so all the non-Bowser characters throw their dices at the same time. Will make the game less tedious and better paced. Game looks good graphically, but character models could use a bit more polish. 

Haven't seen it posted but a new Mega Evolution revealed; for Sableye:

Just saw the final part of the Smash invitational. Amazingly funny and cool! Reggie really is one of a kind.
Also, another moment of E3 to remembre for years to come!

That level where they were riding Bullet bills and Wigglers looked different. It resembled traditional MP more, not really sure. I didn't play much MP9.
