I have 5 open SEPA transfers. 3 of them about 200, one 400 and one of 800. I ordered the transfers: 2013/07/30 , 2013/07/30 , 2013/07/31 ,2013/08/12 and 2013/08/14. One order from 2013/07/26 about 200 I got after 3 weeks.
I didn't have to contact support. MagicalTux explained it on #mtgox today:
13:30 < jouke> Just received an answer on my ticket: "We were bound to certain
withdrawal limits per day which forces the requests to pile up
in long queue. We suggest you to cancel all your pending
withdrawal request and make a new combined single request. So
that it be processed faster."
13:32 <@MagicalTux> remember one thing
13:32 <@MagicalTux> if you did multiple requests, only one can be processed
every ~20 days
In short: Cancel all your tiny withdrawals and merge them into one. It will be processed much faster.
UPDATE:I got my money today, 1800. So my last finished 3 withdrawals:
1800 : 26. August ----> 10. September
217 : 26. July ----> 19. August
200: 23. July ----> 25. July
So I can confirm, that it's like
one SEPA every ~20 days

(from the day one SEPA was finished, not canceled)
I requested a SEPA withdrawal BEFORE you did (23th August) and still nothing from Gox's side. Here you have again the proof that "queue organized in request order" is
.
