With gear (IMO) it's always the typical discussion about whether you need a specific feature (and thus make a very good use of it) or just a "nice to have" and you still can work without it.
For me, the features of this camera are tempting to use them on concert photography and I'm in fact holding to upgrade my Canon to full frame because the only advantage that would give me it's better noise performance, something that in fact this Fuji provides. And I prefer to use APS-C on gigs since we are always shooting wide open and with APS-C you get a deeper depth of field. Still, Fuji's fast zooms are long way ahead to come and it would be interesting to see some honest reviews from the "early birds" in the upcoming months, instead of marketing hype.
For the street, my X-E1 is good enough, may re-consider it when the X-Pro2 arrives, let's see then.
