I dont see them supporting firmware 5.X and above, what i do see, is removing all restriction based functions from 4.5 running consoles, to allow the equivalent.. Maybe even fix the online portion they broke, just cause they got there foot in the door at 4.5, doesn't mean they can open it for anything running higher, like has been said numerous times, the entry point they use is still there in 5.X-6.2, just no exploit to utilize it, they even mentioned there priority was a way of running higher fw games in 4.5
