Fuji published a press-release today on the new firmware version 3.00 for the X-T1. Couple of very interesting new features, some of which are available on the silver edition already, some are completely new. The firmware is scheduled for release a month from today (thus December 18). Read all about it here:

Highlights to me:
  • electronic shutter up to 1/32000"
  • shutter sound can be muted
  • Classic Chrome Film Simulation
  • Unlocked AE-L / AF-L Buttons
  • Q. Menu customization
  • Phase detection AF support for Instant AF
  • Interlocking of Metering and Focus areas
  • PC tethered shooting support (unfortunately no MAC support it seems)

And it seems there's work being done on flash-support. Maybe...

Ow yeah... there's an update for X-E1, X-E2 and Pro1 users too
