Yeah starting to think Carriers are either cancelled, or they're going to be delayed again to some vague netherworld in the future alongside ice planets. Too much time has already passed since the charity livestream - we're back to interpreting Frontier's words in the most backwards, counterintuitive way imaginable just so we can figure out a way to tell ourselves that they haven't actually technically lied or misled anyone.
Queue the apologia: ". . . and THiiiiiiiiis is why Frontier never say anything except for the sporadic and vague Grimm's Fairytale-esque riddle-statement! IF ONLY the community wouldn't listen to their statements, or care about their communications, or expect them to do any of the things they say they are going to do; THEN Frontier would surely communicate all the time."
While I'm just as frustrated at poor communication as the next forum user...
I reckon the announcement for FCs won't come until sometime late March or April. If the last Beta is anything to go by, they won't share details on the features until just a few weeks before the beta, which itself is fairly short, all of which is a short time before deployment. Unless they feel like the timeline needs to be stretched back (and it may, but that's their call) it would be reasonable to assume information won't be forthcoming for awhile yet.
All of which just points to how terrible the communication is. Not mentioning the charity livestream as context would have been better at this stage. Announcements of announcements, vague or not, are rarely a wise choice. Such is FDev communication, though.
