So far, I've refrained myself from talking about Indigo in any specific way. Why? Well, basicly because I know next-to-nothing about indigo, not having written a single service using it ever (not surprising, given the lack of public builds of indigo and not being one of the privileged few with access to it [1]).
That said, let me just say one thing about Indigo: I don't really care all that much about Indigo supporting X or Y specification (but yes, it makes me feel tingly inside as well). What I do care quite a bit about is the programming model Indigo should bring to the table, since so far, it sounds like something I could feel much more comfortable with.
So yes, count me as yet another soul looking forward to the Indigo beta builds :)
[1] The longhorn previews builds don't count, don't have a machine I could ever run it in :)
