Will CI 3 be ready for prime time?

I am about to start a new CI project. I see that CI3 is rolling along. I'd kind of hate for my nice new application to be antiquated when it is released, so I'd really LIKE to start out on 3. I have a few questions for the people who are testing and developing it.

1. Is CI3 stable enough now to start developing against it? Would it pretty much run or crash enough to make me cry?
   
2. Is CI3 likely to be stable enough for a live application in a few months? Not necessarily final CI3.0 but usable?
   
3. If I get done and CI3 isn't stable enough, how hard would it be to devolve to CI2?
   
4. Am I out of my mind?
   

I'm not looking for any guarantees, just a sense of how things stand and how things are going. I think that if CI3 is workable, it should be useful for me to be using it and reporting bugs and suggestions. And I don't really need any help on the last question. It is a forgone conclusion.

Thanks!
