I'm sure they'll manage to fit that in about 5 to 10 percent of the time, same as the other series.
In fact, probably the series that devoted the most time of any to exploration was Enterprise.
Oh come on...90 percent of Voyager was totally new things and places. Everything from the Gamma Quadrant in Ds9....
I would argue that it fit 100% of TOS.
And yes, after they encountered new cultures they of course were about the respective's culture's politics or war sometimes. I have absolutely zero problem with that. I just want the primary focus of the show be exploring new stuff. I don't want a Star Trek-meets-GOT where different characters are on different ships plotting alliances and the great big war of their time...aka the Dominion war with klingons this time.
