Tokio Hotel cancelled?

I was wondering if anyone knew what was going on with the Tokio Hotel show scheduled for May 1st (early show). I noticed it has been taken down from the 9:30 website, and also on the band's wikipedia page it says they had to cancel the tour because the lead singer needed surgery.
I already bought my tickets, so I was wondering if I should expect a refund or if the show is being rescheduled. Any info at all at this point would be great!
This show has been postponed. We are working on announcing a new date. Your tickets will be valid for the new date once it is official.
