Good question. I know I saw this officially stated somewhere - I absolutely remember reading it and knowing it was from Adam or Mark aka official - and not just in irc. I'm 90% sure it was on the support page mtgox.com is being redirected to. It's definitely not there now, though, and I confirmed it wasn't something MagicalTux posted here. If it did come from there and now it's gone I'm not sure what to make of it - my first guess would be just another communication failure, but I certainly wouldn't rule out them deleting it because they had a change of heart. It's real hard to understand why they'd do that though, it'd be the final nail in their coffin for sure if they left the old order book up and forced a bunch of trades at the old market level.
