You can hope they will return them, but very likely you won't receive back all of it. If you can get back 88% then consider yourself lucky.
Is anyone setting up a secondary market in Stampcoins, like the one that was set up for Goxcoins? This means someone buying up Bitstamp accounts at a discount. The account holder gets, say, 75% now, and the buyer takes the risk of collecting.
I am not sure this would be a good idea. I am on the fence as to if the goxcoins exchange was a scam or not. The fact that the operator of btc/goxbtc exchange shut down and prevented people from trading after gox shut it's doors made me somewhat suspicious
