Even though Adult Swim wont tell us what their
brand new anime series is yet, I did a little detective work & discovered online TV guide Zap2it has updated their schedule to reflect AS's changes- sans the mystery. & it's exactly the title I expected it be. There, listed in between the Boondocks & four episodes of Bleach, is a little series called "FullMetal Alchemist." That's right, Adult Swim will be playing the English dub of Brotherhood in only a week & a half from now!
Personally I'm surprised AS wants to keep this a secret for so long. The original FMA was one of their most popular anime titles ever. You'd think they'd be screaming from the hills "Hey, we FINALLY got new FullMetal Alchemist!!" weeks in advance. Well, whatever case, I'm excited. More than likely I'll enjoy the dub over the subbed version that FUNimation's been streaming the past 9 months, since in this language most of the voice cast will be kept the same. Can't wait!

The following link is an old schedule page that they had as part of an older version of their website. The page is no longer linked anywhere on the current AS site, but the schedule still gets updated regularly- even further in advance then the current schedule page. It too lists FMA at midnight:
