I still dont think this will happen any time soon, if at all.
I just dont see the demand. We are not exactly crying out for an "up rezzed" version of TNG. Also, its going to take forever. They are currently knocking out the TOS at the same speed that they produced the original show. One a week.
Are we going to wait another 7 years for the TNG stuff to be remastered?
I think not.
