I can't stop loving the Video module on the controller, I don't know how many times I played dreamcast and was like WHY is NO ONE else doing this. Now you can successfully hide plays on sports games when playing with friends, as well as other awesome things (like power ups Mario kart, how awesome is it knowing you've got a blue shell, and the guy ahead of you is smug-facing because he thinks his banana is gonna save him.)
Oh man, I forgot about Mario Cart... I spent so many drunken hours playing Mario Cart 64 in college when it came out (when there wasn't a party to go to). well, that and golden eye.
Don't get too giddy, this is going to fracture the market even more. Sony and MS come out with consoles a year and a half to two after, much more powerful, and yet again you have the disparity and the Wii is getting shovelware. They are breaking themselves off even further from the pack with this, which will strain any developers that aren't Wiiii exclusive.
