It's probably a mixture of both. This is speculation, that's what I am doing, what you are doing.
Don't attack me because I offer a different opinion.
Your options are:
Sell now and withdraw asap. Some are doing just that (price is creeping down slowly) But that means you can't get anything as long as you aren't verified.
Wait till you are verified and sell then.
You can if all fails withdraw you coins and sell them somewhere else. But still gox offers the highest prices so people think it is worth waiting. Added to this other exchanges lack liquidity.
A rational trader would maybe do it like you described in the second option, but I think you give the panic sellers too much credit here. imo most have sold first, then started thinking about how to get the money out.
Lets wait and find out.
