The T.V market is not the same as it was in the 90's.
If they did make a new Trek, it'd have to be on HBO in order to get the budget required.
There is too much money in cheap Reality TV these days, hence why you don't get that much big budget TV shows like Star Trek.
It would have to be different than TNG era trek was i'd wager.
If anyone has read the Vanguard novels, I think that would make a fantastic, HBO produced show.
