Why are developers still calling games for current gen consoles (Next-Gen)?

Agree. Next-gen is an anti-Wii buzzword, and will likely endure in the Wii U age, making it an anti-Nintendo buzzword

Of course it'll continue with the Wii U, we already have people saying it won't be next-gen even though we don't know everything about it.
