The word "stoked" comes to mind and it still seems to be an understatement.
There are a lot of rumors on this thing being very pricey though ($300 you can buy all of the major systems for that price). This kind of saddens me and I hope it is only a rumor as it will weed out a lot of potential buyers.
I am definitely looking forward to the library of games on it though. OoT, Starfox, Kid Icarus, Professor Layton vs Pheonix Wright? A list of titles.
