This seems to go well with the comments I made about FF yesterday:

I don't think they'll call anything new on the publicly-released roadmap a DFA or FA right now, since no FF camera is announced. But a FF does seem to be something Pentax has been talking about recently, if you read between the lines.
The * zoom in 2013 clearly looks like a 28 (or 24) to 70 (or 80) f/2.8 lens. Traditionally, this focal length only makes sense on a FF camera. In other words, they are essentially "bringing back the FA*28-70," which I said was the only essential lens missing if a FF camera is to come out. Since it's in 2013, this indicates that a FF camera likely wouldn't be released until toward the end of the year, at the earliest. But it also strongly suggests that they
are bringing one out. This time frame (late 2012 or 1H 2013) also fits within the time typically needed to develop a new camera, if measured from the time of the Ricoh acquisition. I think they could get away with a ~24-70/2.8 * trailing the camera by a few months, but they would likely announce it around the same time.
(True, I did say the FA*80-200 also needs to come back, and it does, but they could get away without it for a while, considering the DA*200/2.8 prime and the DA*60-250/4 work on FF. But they
do need a ~70-200/2.8, eventually (I just didn't want to say they could put it off yesterday, because it's a poor idea). Sony has an outstanding lens in this category, as do Canon and Nikon.)
Hopefully the DA Wide Zoom is the Tokina 16-28/2.8, or something similar they are developing. This is the third of the three lenses I said they need for the FF.
The DA Telephoto at 550mm fixes the glaring absence of lenses over 300mm right now. It will be curious to see whether it becomes a * lens before release. Perhaps they have some new naming conventions in mind.
The DA Zoom Ltd is the most intriguing. I would expect it to be FF, most likely. This may almost make up for the lack of any current FF lenses below 31mm, even though it's not a prime. It looks like about a 24-35 or 24-38. Remember, Sony Zeiss and Nikon have shown us some outstanding wide zooms lately (Zeiss 16-35/2.8; Nikon 14-24/2.8 and 17-35/2.8). Once again, 24mm sounds like something destined for FF.
The DA 50 almost certainly replaces the FA 50/1.4, since it's the only non-Ltd FA left - I can see it going at either f/1.4 or f/1.7 to f/1.8. A 50/1.2 might be a better use of engineering resources (since the DA*55 and FA50 can keep going), but I expect a FF capable lens similar to the DA35/2.4 (another positive sign - why else make a new 50, if not partly for FF?). But I'd still love an AF version of my K50/1.2 instead.
Anyhow, who's to say a DA lens can't be FF? That's just the way it was in the past. I won't be surprised if something in the naming changes on at least one lens, whether adding a * or Ltd, or changing a name to D FA, or perhaps a new variant of the DA name.
