Next level cap

Wondering when the next class unlock is going to come out. Also curious what the predictions are for the number of each upcoming increment.
My guess is there will be a total of 7... Being a Dragonball game and all.
So 300, 600, 1000, 1500, 2500, 5000, and finally 9999/10k. Oh and what exactly are they going to name them since this one is called Master...
Mega Master, Ultra Master, Maximum Over Master?
