There is no Endgame 2. I don’t know where you get that idea unless you got it mixed up with Infinity War Part 2, but that was renamed to Endgame a long time ago.

It’s been playing since last July. Just wait for announcements regarding the dub because licensing for Dragon Ball material usually takes a long time.

At least you’ve got GT and the movies to keep you occupied for a bit. GT is an okay series. If you watch it, do it with English dub and Japanese music (which is on DVD) or Japanese voices and music. The dub’s music in that series is very lifeless in my opinion.

That’s because a lot of people have already been seeing it via other means.
