Now we have to wait what is the desire. One would imagine it's everyone's return to adulthood and there Goku would transform into SSJ4 as he should be. But seeing how everything is going I don't trust anything. I didn't like the transformation either, basically because I found out about spoilers and of course, the aesthetics fall short.
It was very anticlimactic. I hope the excitement comes back a bit. And well, all the GT fans can rest assured haha.
Cheers bro!
