@maxterdexter:
I can't trust my memory on that one, I've only watched the saiyan arc once (without DBZA), and still haven't pushed myself to read the manga to that point.
@Green_vs_Red:
Dub mistake as noted by the above response on my part.
I dug out my volume.
DBZ volume 4, Viz Media, page 69:
Goku: "My grandpa….you killed my grandpa...!"
Vegeta: "Ha ha, now that is a good one!"

@fana:
I still think that U7's wish will be to fuse all the erased universes together with U7 (a solution to Zeno wanting less universes). .
This seems like the better outcome with the circumstances we have right now. Wishing all the universes back straight up would be too predictable and would make the arc feel pointless. At least that changes something.
