The only fully "current generation" forums we have are the BW and BW2 forums. Trade Corner and Battle Center both contain threads for past generations, so they're about as current generation as Pokémon Gaming Central is. Fourth generation isn't current either. I suggest renaming "Current Generation Pokémon Gaming" to "Primary Pokémon Gaming Forums" or something similar.
Perhaps the Pokémon gaming forums could be reordered to something like this?
I prefer the second format, but the downside is that BW and B2W2 will be pushed down some. Other than that, I think the second format looks more organized than the former and what we have right now.
