24MP would be nice in an X-T2, but unlike others who are adamant that it's a "must have", not sure that not having that would be a deal killer for me. What would be is a lack of substantial improvements in the AF subsystem, both in terms of low light AF and tracking. Probably the biggest complaint I've had (and read from others in various forums) about the transition from DSLRs to Fuji mirrorless has related to challenges in using their cameras (X-T1 in particular) for sports, wildlife, BIF, etc. If Fuji were to take a hint from Sony and invest heavily in improving their AF and delivering reasonable DSLR class performance, the X-T2 could be a true killer camera. Their lens selection (plus roadmap additions) already would meet most photographers' needs. A major improvement in AF would be a real game changer, IMHO. What's listed in the rumors so far is pretty well a big "yawn", however, I'd have to believe (and hope) that Fuji has more up their sleeve.
