There are credible sources claiming that the Dragon Ball Heroes game is getting an anime adaptation come this July. Should be interesting considering the game is an amalgamation of all of the forms including SS4 and the god forms.
As of last episode he has achieved Mastered Ultra Instinct, which isn't a form exclusive to Saiyans. Essentially, the form is the culmination of being able to move without being held back by having to process movements, which, in the show, is represented by being unable to see their attacks. For comparison purposes, this form is more or less around that of the gods, like Beerus.
Jiren's wish has me thinking, wouldn't it be interesting to not only revive his parents, but all those unnecessarily killed? Pretty sure this would be in bounds of the Super dragon balls and make for an interesting plot. Planet vegeta restored, Jiren's parents restored, and Universe 13 (which we've heard nothing of after its introduction)
