Site gets put back online next week with a rebrand (just a new logo).

btc withdrawals limited to 5btc per day\week purely to stop everyone running with coins and keep the business viable.

Mark announces step-down and takeover from a 3rd party. new CEO publishes a statement listing features\optimizations to the trading engine, altcoin implementations etc to help evolve the business and distance itself from the 'old' mtgox. financial reports published each quarter (similar to bitstamps last announcement).

in a few months, or whenever deposits seem to have built back up and confidence restored, withdrawal limit removed and trading fees reduced as a good will gesture for a set period to entice customers back that fled on the re-opening.
