It's a interesting feature set, though dispenses with an OVF relying on the EVF from the X-E2. To me it's a bit like have an EX-E2 with a smaller sensor and a fixed zoom lens, with the added benefits of tilting screen and full wifi remote control (like the X-T1), hopefully the latter will come as a firmware upgrade on the X-E2 in the near future.
Nice camera, evolution rather than revolution, though initial Fuji pricing will put some off, Fuji's have a habit (like many cameras of taking a price plunge shortly after release).
Note Currys/PC-World seem to be doing in-store deals on the X20 at present, as low as £229, which is less than half the price of the X30
