I'm somehow positive about the DF part, of course combined with the 3 haki forms. Let's see it this 4 options.

First, he had a DF which we still haven't seen, and now it belongs to someone else. Secondly he had Ace's DF. Why not, he is his father. The fire fruit. The third option is the Gomu Gomu no mi. We also known he had the SH Luffy is carrying, so why not the fruit? The fourth, and the one that is very popular in these discussions is the Weather fruit. If Dragon has it now, Roger could have had it before. Remember chapter 0, the Edd War battle.
