Think about it...
Think the opposite. If they've lost this many coins, then there is literally no way back. They would have said by now, why stall the inevitable?
Collect fees on people trading during the uncertainty while meanwhile, management moves behind the scenes to minimize damage to their personal assets and perhaps look for investors to bail them out. i suspect that this is what mark and his inner circle are doing now.
Who will invest in someone losing 750k coins?
they don't necessarily need to cover all the lost coins to give the impression that it's business as usual. but the fact that they've been down for this long and recent actions strongly imply that something is seriously wrong with their accounting, perhaps to a greater degree than they originally believed.
i too doubt any investor would want to step in to provide emergency relief to mtgox, but that wouldn't prevent management from seeking out such a party. this would explain why they're remaining quiet with no further promised dates for updates. they could be trying to save the company, but until something goes through, they can't make any comments.
It's a good theory, I agree.
Despite this though, that article is pure steaming shit
