There will be some features that will not make it as I'm sure some of my ideas wont work out once we start testing them with real users, and there will be some I haven't talked about will be in the game that everyone will wonder how we could have ever conceived not having.

Part of the reason of doing this with community involvement from the start is to make sure the people that will be affected by some early choices have a voice int he process. Perhaps its feature A or feature B at launch. Backers will get a say in which feature is more important to them. Its not a perfect process but I think it will be the bets one for the long run - and as a lot of people have noted just a sub set of some the proposed functionality will be pretty awesome and I'm not going to stop until we get it all (that makes sense from a fun / payable / balancing standpoint)
