This is true because they have all they can handle. They would likely rather expand to another platform than develop for the 1.8s.
Could be.
Who knows. Maybe they'll surprise us and come out with support. If they had MPI for the 1.8t, it would be a no-brainer for me, personally. I had Cobb on 2 cars before (Wrx and Lego GT) and would gladly jump back in if they had the features I need.
