Unfortunately I have no idea because SmileBoom hasn't mentioned its release schedule in US yet.
Neither, Nintendo hasn't clarified detailed specification of Switch yet, therefore I cannot predicate that it'll be available on Switch.
WHAT?!? SmileBASIC Wii U exists?? I guess it will be a long time before it shows up in USA, though. It sure took a long time for the 3DS version to come out in USA.
Petit Com BIG (SmileBASIC for WiiU) has been released since the middle of last month in Japan. Almost all source codes for SmileBASIC are also available on Petit Com BIG.
I hope it'll be released in the US asap.
No matter to me. I don't have a Wii U. Still, it seems interesting, and I do know some people who have a Wii U and I would like them to try this. It seems that, from what I could gather on SmileBoom's Japanese website, PetitCom BIG (SmileBASIC BIG) costs 3 times what SmileBASIC 3DS (PetitComputer3) costs. But I'm seeing advantages, like multiplayer games being much easier to make. That sounds cool
