A potion of a Siliconera interview with Suda51...
S: Is Travis Strikes Again going to have a retail release?
Goichi Suda: Maybe. Grasshopper Manufacture is handling publishing for this title.
I don't really care about getting games physical or retail, as I just want to play the game any way I can. That said, since I'm such a huge fan of the No More Heroes franchise, it would definitely be nice to grab a retail copy of this one.
