I guess it's more likely that it'll come out Q1 2013. I hope we'll get some more previews soon. The minigames they've shown so far look good, but i'd like to know more about the game's structure and modes. I'd also like to know how many games there will be in the final version.
This is on the top of my BUY list... I've loved all the WarioWare games... ("Touched" being my least favorite - "Smooth Moves " being #1 to me... "Twisted" right behind it). This should be a RIOT! Can't wait!
