Couple of things I figured I’d say about Umineko.

• The anime is surefine so far but gamefags are going to ruin it for anime-only viewers with all their complaining. If you gamefags want a rushed story, go watch FMA:Brohood where everyone, including non-manga fags (me), can feel it’s rushed. You’re also making it sound like Umineko was supposed to be some Key/KyoAni CLANNAIDS drama - I’m glad it’s not.
• The new game, Umineko no Naku Koro ni Chiru: End of the golden witch, is coming out on the next Comiket (C76, August 14-16). The new OP is available here - as Kaze said, it’s a Kanako Ito wannabe.
• The next Comiket will also see the release of Dai’s 2nd Umineko related album, subtitled “musicbox Blue”. In addition to old stuff it apparently also includes new BGMs from Chiru. More info here. Update: “musicbox Red” featuring music from zts will also be out during C76. More info here.
• Umineko Episode 1 (Game) Original Soundtrack is supposedly also coming out on Comiket, then followed by an August 26 selected store release with KNIL-0004 cat# (Akiko Shikata’s OP was KNIL-0003). Not much info is available about this product at this time though, it might just be a rumour. It’s now on getchu and animate so it’s confirmed.
• The first two character singles for Umineko are coming out on October 7 and November 6, 2009 (FCCM-0290 & FCCM-0291).
