SmashWiki:Upcoming appearances tracker

For reference. My attempts at keeping track of which games' releases will warrant updates to character pages' "most recent appearance" data. I skipped listing anything that doesn't have a character template with such a row (e.g. Goomba). Others are free to use this as a reference or update it. I've also listed any game releases that will make updating the "most recent game" of the series necessary, in addition to those with characters we need to note.
