The Features: So what will be new with this X-T1p (or whatever?)? The viewfinder! According to both, the anonymous source with nick-name and one trusted source, the viewfinder will get a 4.0k upgrade from the current 2.36k.
The Announcement: According to both, the anonymous source with nick-name (ASwN) and the trusted source (TS), the release should be in July (first week of July, according to the ASwN-source).
I'm thinking Fuji is so far ahead of the pack with this one, they will look at other stuff before upgrading the vf. The XT1 is way less than a year old, chances of a new version are slim at best.
