I realise that, but I just have no clue what the cost would be. As the price of remastering TNG is the issue here, it would be nice to have some sort of estimate. We know its going to be substantially more expensive then TOS-R. So knowing what the costs of that was would at least tell us what kind of range is considered feasible.
I really have no idea what the cost would be. To come up with an estimate, I would imagine you'd take the cost for a weekly SF series already in production (TNG's original cost 20 years ago was between 1.2 and 1.5 million dollars an episode), take away the production costs leaving only the pre-production and post-production costs. Then add money for extra costs like finding and cleaning up all the film.
