Loool, and everyone said I was a fool when I said that they couldn't possibly patch the game via wi-fi.
Their "patch" as described in that quote is to simply fix games that haven't been bought yet, which would lose them a lot of money.
I find it funny how they only mentioned one shortcut, not the several that have been found (although admittedly only one is game-breaking so that noobs can gain an almost uncatchable lead).
At least they admitted it though, I wasn't around near the start of mkwii, but I don't remember anyone ever mentioning that Nintendo admitted the glitches on GV and MG (the first two).
Actually thinking about it, considering they say 'it would give people with newer consoles an unfair advantage', this makes it sound like that in a way, they don't mind people doing it

Anyway, the idea to do the glitch in ww and no-glitch in community still works well I guess.
