UPDATE: My LBS says BMC is "noncommittal" about the ETA for the fork. They claim they are sending out forks as they receive them but mine (the first one ordered under the recall in this state) apparently hasn't yet made it to the top of the stack. I haven't heard from anyone who has received one. My LBS is a big multi-location BMC dealer, but he hasn't received any.

He says optimistically that we should receive my fork this week or next. But he doesn't really know.

My original guess of April 2020 is looking more likely by the passing day.
