Great! I was worried the game wouldn't support vocal chat and my buddies and I would have to sit silently next to each other on the couch as we played.

I bet yal are gonna be rage'in hard! :L

Would be hilarious if we had to type everything

I hope it is only with friends.

I'll probably mute it if that is the case. Most people are annoying and hearing their shitty voice doesn't add anything to gameplay. Most people just talk shit anyways.  I wouldn't mind being able to talk to friends but I don't care to talk to random people.

It would be great if it was only friends. 

I seriously mean it when I say "No offense to anyone here," but when this is a big bonus you know that your console is massively behind the competition in the online department.  This is a perfect example of why it is having trouble competing with last-gen devices.  

Be good if there was mute all except friends option along with mute individual or all.

i finally get the opportunity to chat with my friends while playing mario kart :O

It's 2014 and we're excited about a console supporting game chat? -_-
