I can't remember where I read this and I don't remember all the details, however: As I understand the problem is mainly with USD withdrawals to USA, and the problem is not with MtGox but rather with the bank they use having some legacy issues and that they can only process X transactions a day in batch. Or something to that effect. For this reason I switched to Bitstamp and the experience is night/day different.
