Roaming the site, I'm seeing more and more pages that haven't changed since Black and White came out (or even, Diamond/Pearl/Platinum in some cases!)
The most glaring one of these is the index for the anime, which doesn't list seasons past the second Sinnoh series. The "other games" section is also missing Mystery Dungeon:Gates To Infinity (and doesn't have a separate link for the N64 Puzzle League, but that's sort of nitpicking.) The TCG page also doesn't list any sets released in 2013.
I do realize that these are some of the lesser-traversed pages here, but they should be kept up-to-date to make this a viable resource on Pokemon.
