Well I made a deposit of 1 BTC just a few minutes before the announce.

Took a bit, but eventually it credited.  I immediately put in a withdrawal request and it looked like it worked.  Only time will tell if I get ever actually get my coin back.  But here's hoping!

Will update here if/when it does.
