Not that I know of. Really all I've heard so far is it's going to be more inquiry driven (have less personality) than Sir I and that- optimistically- it will be released in some form (whether alpha/beta/final is unknown) in January or February. In other words, you could get it tomorrow or a year from now. Or, depending on your phone and how they decide to work compatibility, never.
In any case, while I agree this is exciting, it's probably a mistake to get your expectations up, at least in the near term.
