if they were gonna take the money and run they would have stopped withdrawals when the power went off...anyone would know that in a scenario like that there's gonne be a huge chunk of investors that freak out and withdraw as much as they possibly can.
Option 1: Stop withdrawals, he can get some of the payouts that were not moved out
Option 2: Claim that everything is working again and lure people for new money with the cheap KH price. -> would be my choice
Be honest: How many of you will now send some BTC in scrypt.cc's warm und fuzzy wallets to buy some cheap KH?
