For that reason, I wouldn't expect a large proportion of Gox account-held-BTC owners to rebuy. They're not going to think "damn it, the $200 in coins I bought 2 years ago could have bought me a new car--now I'm going to chase after $500 BTC!" They'd probably think more along the lines of "easy come, easy go." That's certainly what I would have done if I hadn't withdrawn almost all my goxBTC in late January.
If they thought like that it means they were going to sell them, which would push the price downwards. Their loss translates into a higher bitcoin price even if they don't rebuy.
