My assumption is that he'll have the horned Hollow mask that Hollow Ichigo had, or maybe even the horn fragment that Hollow Tensa had. Whichever one, Ichigo will definitely still need a Hollow mask to use his powers.

I have my doubts that Ichigo will ever resort to using a Cero; as Ulquiorra once told him, his Getsuga Tenshou already resembles one greatly. Assuming those became even more powerful than they were before, I doubt that he needs any other energy attack, unless they have some interesting property that would make them useful.
