SO i was reading the newest chapter and realized that the "new guy", Stern Ritter D, Askin Nakk Le Vaar, totally resembles this guy from 494:  (who totally has the same big lips, nose and you can even see a strand of black hair on his left side)and he also has the same hair as the guy who fought Ukitake, too.
It would make sense, as both of these aforementioned Quincys haven't been accounted for since, and we have seen all the others.
Also its pretty obvious the creepy eye-staff black Quincy is the same as the one who attacked the RDI during the invasion. (same laugh.) Plus he looks creepy and the fact that he attacked the RDI makes it seem like he will be going up against Mayuri in the future, a perfect Quincy counterpart for Captain Kurotsuchi to butt heads with. >:D
