The Umineko domain
http://umine.co/ is now divided into several subsites for 推理と魔女の輪舞曲, 真実と幻想の夜想曲, 黄金夢想曲Ｘ and うみねこportable.
The PS3 version of Chiru still has no content, but the page for the PSP version is already quite updated
http://www.umine.co/portable/.
I personally love the cover for the first game. The second cover depends on what the colour is going to be...of course they'd use Ange and Eva-Beatrice, but I hope the colours will match. And I'm pretty excited considering they already inserted slots for vol. 3 and vol. 4 announcing they will be EP5 & 6 and EP7 & 8.
In an interview it seems Ryukishi already announced that they will follow sometime next year. Depends on how trustworthy the sources are and if they really did quote Mainichi Shinbun Digital...but it would be strange for them to mention them on the official page if they had no plans for actually doing them.
So...YAY for not having to buy a PS3 right now after all.
