Fujifilm Finepix X50 camera is indeed listed in the Promaster catalog
I was wrong. After my Fuji X10/X50 post yesterday, a reader (thanks Steve) posted a link to the somethingawful forum that contained a picture of the new Fuji X50 camera from the Promaster catalog, which existence I previously denied . The catalog must be out for few weeks now - the first time I asked about it on Twitter was on August 6th.
Here is a scan of the Promaster catalog listing:
The other news is that the Fuji X50 will have a viewfinder. The rest of the rumored specs can be found here.
