What ever is next would have to work within what has already been...I mean...TOS is being done in the movies...would TNG, DS9 & VOY be ignored? These shows are institutions as much as TOS. IMO.
But try telling that to anyone in Hollywood right now. Somewhat obsessed with remaking everything they remember seeing when they were 8 years old, rather than continuing where those same long-running franchises left off, or heaven forbid, doing something completely original.
Hollywood sees re-telling popular or even familiar ideas safer than doing something new.
