One of the things I would always recommend if you are working in the Microsoft stack at bleeding edge I would start trying to talk to the evangelists sooner than later. It feels on the outset that this is how their product cycles work so making friends with these people can help you get past the 'on rails' presentation of the demos. I say this as someone who goes to in-person presentations from these evangelist types and poked holes in their demos and got satisfactory admittance of guilt or meaningful follow-ups.
