Isn't Eric the largest shareholder, and unlikely to dump them quickly, if at all?
While some shareholders may dump, I suspect the sell-off won't be as big as some people anticipate.
The kind of people who buy shares in an enterprise like Satoshi Dice are often either Bitcoin faithful (more likely to hoard) or gamblers (more likely to bet on the more volatile currency).
Yes, there will probably be some dip, but not enough to say goodbye to $100 for more than a few days.
