In the above link it states that the release date for Raspberry Pi Fedora Remix 17 as May 2012 (although it is in brackets!).
That will be the beta for the Remix based on the mainline beta 17.
However, according to the Fedora Project site:
the mainline final release will be May 22, 2012, although that date has slipped twice, but, only by a couple of weeks since release planning started in November. I don't see how in the world they're going to have a stable Remix 17 based on mainline final release 17 only two weeks from now. Very few beyond the Seneca team have Remix beta 17, and there are still a relatively small number of Pi boards that can test it.
I'm guessing that they won't be able to declare Remix 17 stable until there are enough users with Pi boards to do adequate testing by late in the Summer, maybe even the early Fall, per the guesstimate schedule I had recalled. This can't possibly include desperately-required things like a GPU-accelerated X window port.
The best things in life aren't things ... but, a Pi comes pretty darned close!
