Earlier in the year I banged on about the TriCaster after I had a demo. We've just finished an install at the College of Law using it as the centre-piece of their little three camera studio and I am even more impressed than I was! Driving the virtual environment is so easy and it really does perform well. Having a selection of four shots per camera (you set the shot for the close-up and then each camera is available as the close-up, MCU, twp-shot and long-shot) with an environment that tracks perfectly is a revelation. The in-set virtual monitors work as well. The perspective and reflections on desks etc are all very convincing and once you get past the fact that all the virtual sets look like CNN or ESPN you can really produce some expensive looking tele.
I hope Root6 pick this up as a product because there is nothing to match it sub £100k.
