I know how frustrating can it be when people tries to hasten your development, I don't want to do that. But I think a lot of people would like to know around which date are you planning to release the beta. Also, I think a lot of projects' deadline might depend on that.
Although there are quite a few people already using 2.0 (or packages of it) to build applications, realistically I don't think it will be production ready (i.e. an official 2.0 release) before the summer.
