With free software (or $299 software allowing easy collaboration) and a starting pricepoint of about a thousand dollars for the simplest control panel, which looks like it should be quite adequate for HDTV-level projects. Maybe not up to easy handling of full movie-quality work, but if you're getting the proper hardware kit for editing such movies, a $30k control panel is not likely to be seen as being outside the reasonable.
DaVinci Resolve's color-grading features are every bit as good as any of the movie-quality applications. It has shortcomings in other areas, but its color correction is really second to none.
