I think you'll be better off just waiting for Kaiju Combat on the Wii-U. I'm already planning a "re-work" of the original G:U story - so you can have all that fun with a better underlying combat engine & production values.
I'm always down for some more monster combat, so let's hope this comes through! Thanks to GoldMetalSonic for the heads up!
