A translation of moonphase comments follows
"To be officially announced on the cover of the 20th volume released tomorrow, If the information leaked from BONES is correct, it will be directed by irie yasuhiro; if the prior information is correct, it will be an anime adaptation true to the original, running for 1 year starting april of next year at 5 pm on mbs/tbs."
All we can confirm at the moment is that there will be a new FMA anime series. Everything else from the moonphase comments section can be classified as 'rumors' for now.
It is now a reality, and we have FMA: Brotherhood anime series!!
