I'm happy that Takuya wants to finish up his older themes. Shows how attached he is to them in wanting to get them as perfect as he can. Also this means good things for us Europeans if it will help along the Dancing Stage themes too.
Personally I can wait for Supernova Beta 3. I think we should all relax in the comfort that when Takuya does get back round to theming Supernova its going to turn out bloody brilliant if he's as passionate about making it as perfect as he's making Max2.
