Umbraco v5 dates?

we are starting a new project and I would like to know if V5 will be release soon, cause you know that MVC is way better than webform so I would prefer wait a little bit more and work with MVC than start now on top of 4.7 and work in webform but when I try to find any docs on umbraco v5 aka Jupiter it seems like it wont be in Beta before a while. I know that next week they have CodeGarden11 and they are supposed to talk a lot about Umbraco 5 but I don't find a lot of documentations except this for this link : http://jupiter.umbraco.org/

Anyone has more informations?

Thanks a lot!

Edit : I found this to use MVC with开发者_开发知识库 umbraco : http://our.umbraco.org/projects/developer-tools/mvcbridge if it can helps anyone else.

Umbraco 5 RTM was released on 31 January 2012 (but discontinued shortly thereafter by the developers).

Umbraco 5 has been cancelled but continues to live. A small team of developers has forked the project:
