To contrast some reports that SEPA transfers are now fast, I just yesterday received a 1000 SEPA withdrawal that I made on May 8th 2013 (so almost 4 months). Previous payment I received was on Aug 14th for a withdrawal made just day before on May 7th (also 1000). I have 2 more 1000 withdrawals pending made on May 10th and May 14th.
Since apparently some people are receiving SEPA withdrawals with minimal waiting, the claim that Mt. Gox is working on a "queue" is quite laughable from my perspective. My theory is that everybody receives "something" every few weeks in effort to calm people down.
