Okay so I haven't kept up with what's going on in the Dragon Ball universe until just now. Watched Dragon Ball, DBZ and Dragon Ball GT years ago (and I mean like 8+ years ago) so my memory isn't that great.
I never saw the last 2 DBZ movies either, so this is all new to me.
One thing that's been bugging me is: is Videl's child still Pan? Is Pan still going to be part of the series or are they retconning her out?
It doesn't look like Dragon Ball GT is canon now either, but that was never really that canon.
Also: Can Goku still go Super Saiyan while in Super Saiyan God mode? I wonder if we'll be seeing much of SSJ3 now that he can transform into a god. Also I wonder how big of a role the other Z fighters will play in the new series considering that they're all super weak and left behind now compared to Goku and Vegeta.
It'd be nice if they brought back a little of the original Dragon Ball story telling and less DBZ style 10+ episode long battles with long filler dialogues inbetween.
