I bought it in 2D last year, just wanted to watch it on the new set, and it looked great. I plan on buying 3 in 3D soon, and rewatching with the wife (she loves bayformers). We saw it in 3D in the theater.
With the black performance of this set and the new speakers, can't wait to see Dark Knight. It'a amazing going back and watching something you've already seen, and realizing it sounds/looks even better. To me, this is whats hard about AQ/PQ reviews. Depending on your setup, you can have a different experience from the same movie that others do.
