Kraken exchange rate

[thelaughinggravy]

When I look at Kraken I see:
EUR/XBT: €492.95713 / 1  and USD/XBT $676.58714 / 1

why is it so far above MtGox for example which is W.Avg: 392.95 € / 1

Data as of 13/02/14, 12:16. Am I missing something obvious?

Yes you are. Read up on recent news about Mt Gox and you'll see that if you but Bitcoins there you can't get them out of the exchange. Hence the lower price

Hm. Getting out OK. But can't I easily transfer bitcoins? (not cash). So buy into MtGox, shift bitcoins to kraken and sell there for cash? Or is it really hard to get the bitcoins out of MtGox? (I thought the hard thing are cash withdrawals.)

//edit:

ignore the above. So liquidity / uncertainty is really the only driver of prices between exchanges. wow.
