Here is my opinion:
1. The racing will be good, the track is really smooth.
2. The closest track I can compare the groove and feel to would be the old WFO Raceway, minus the bumps.
3. The lower middle seems to be the fastest, which opens the very bottom for some big slidejobs.
4. If you're up high you can run side-by-side with the guy under you by using the momentum on the high side.
5. The slidejobs have to be carefully planned and seem to work better in turn 1 than turn 4. Reason being is that in turn 1 if you run the fastest line (the fastest line I tried) then you have to lift just a little while the person doing the slidejob can go in wide open and let it slide up in front of you. In turn 4 you can go wide open on the same line that you have to lift on in turn 1 and so it's really hard to clear someone by doing a slidejob in that corner, so hopefully people will be careful with them. It should make for some fun and unique racing.
