I don't get why the rest of the markets (Non-Gox) go up if there is really a remote possibility of Gox enabling withdrawals, Can you imagine the amount of bots that are ready to transfer everything from Gox to BTC-e, Stamp, etc and close the arbitrage gap? The bigger the gap is the bigger the benefit (and the crash in the rest of the markets).
IMHO you should be in fiat on the rest of the markets and wait to buy when the arbitrage starts...
It's probably a bit more complicated than that. It really runs down to the following questions:
1) if (and if so, to what extent), and when will gox allow btc withdrawals again
2) assuming withdrawals are reenabled, how will the price difference be settled
There's the, plausible, I admit, scenario that cheap coins flood the other markets, and selling pressure will drive price down on stamp and the others.
But there's another observation that shouldn't be ignored: gox and stamp prices (to pick out the 2 big Western exchanges) have always been highly correlated. There's a large gap between absolute prices, but the correlation still exists (although I suspect it is lower now than it was 1 year ago -- I should look at this again).
That said, here's the observation: in the last week or two, it was apparent that stamp was rather reluctant to follow gox in its tumble to zero. There is no "instrumental" reason I can think of (as in: some obvious way for automated trading profiting on stable prices on stamp vs. falling prices on gox), so large scale manipulation non-withstanding (which I am always rather sceptical about as an explanation), I consider another interpreation:
The crash on gox revealed buying pressure that lay dormant in the otherwise "overpriced" market. Similar to how the SR closure started the rally, because it revealed the pent up buying pressure by bringing price temporarily low enough for the sideline fiat to enter.
Note that I'm unconvinced the 2nd explanation is the right one. I'm just pointing out that I *can* see another way for the price difference to resolve, other than the other exchanges being brought down by cheap gox btc.
EDIT: stable, not rising prices on stamp
