2.5+ hours since Bitfloor shows my transfer as completed (Wed, 17 Apr 2013 22:38:15 GMT) still no sign of funds in the block chain. No response to my email to support as of yet.
Given the circumstances, it's possible they got inundated and are working through a backlog. I remain hopeful.
I initiated mine at 5:30EDT It's just now showing up 2 confirmations...looks like everything is processing, just slowly.
