I hope they differentiate between the hair colour and rigidness for Super Saiyan forms like in BT3
i.e:
Namek era Goku had softer whiter hair like this:
Same for Trunks.
Then in later episodes it was more yellow and rigid:
This, in addition to the period correct Gi for Goku etc. is why the Tenkaichi games are the best.
I hope this accuracy continues!
