Technically, Eclipse is on indefinite leave rather than officially dead. The torrent archive is still available on their website and they say the IRC channel is still active. It sounds to me like they all grew up an got lives that forced them to give it up.

It was one of the classier acts out there, and they went out with class too. They say they will finish Kaichou at a slow pace, but they are stopping Amagami at ep. 12.
