I'd rather expect them to wait for the villains to be ready and the original story mode to be redone. Regular updates on the same principle as SF5 would be fine, but given what even the first PSP game had, it would be a shame to not start with something close enough. Maybe next year.
(I don't want people to blow up over this game like they did SF5 for having a laughable story prologue and no "arcade mode" or single player content beside survival - but then again, not the same crowd)
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
