Let's look at what the mid-June rumor site actually said:
Previous rumors have the K-3 sporting a 24MP sensor, 29-point SAFOX X/w light wavelength AF sensor, 6fps continuous shooting at highest resolution, 1080p and 720p video recording at 60/30/25 and 24 fps, Dual PRIME M processor and ISO range between 100 and 25,600 (expandable to 50-102,400).
Today we found out that the K-3 will likely be announced at Photokina in September and launch in early 2013 under the tagline: “the world’s most compact full frame.” It’s expected to use Sony’s new 24MP sensor (possibly the same one as the D600), come with a brand new kit lens, battery grip and flash unit, and sell (body only) for around $2,800.
Considering the rumored sensor and the fact that both the Canon and Nikon entry-levels should have significantly lower price tags, we’ll have to wait and see what other features Pentax is planning to bring to the table to lure photographers their way.
Ok, those specs look a lot like the replacement for the K-5 and would be great on an APS-C. But Norm's points about how it measures up to the current FF crop of cameras from the big two make it look a bit anemic if compared to them. So, is this just a rehash and recycle of all the rumors we have already seen so many times or is this a misunderstanding by some Chinese camera enthusiasts about what they had leaked to them from a friend at some factory but it was garbled from APS-C to FF? Only time will tell.
