I still see Infernape's Nasty Plot set being used. I really see, at this point, that the majority of Blazikens will be physical, and Infernapes special-based. They both have their advantages and disadvantages.
Blaziken, when given a turn free/safe switch, will be faster, and hit harder physically. Infernape has more immediate speed on the first turn, and has the option of going both Special or Physical more easily with respective boosts, making him more unpredictable.
