Does the D-FA 50 f1.0 lens really exist?

Damn that’s a news! You remember the leaked image from the Pentax K-7 showing a 1.0 aperture on the top LCD. We all believed ths was just a fake. Now a new image is showing us the D-FA 50 f1.0 lens on a fake/real Pentax roadmap.
And here again the “old” leaked image. So may this lens is REAL???


Funny thing that this fixed focal length lens would have a petal-shaped zoom hood, isn’t it?
I’d like to have one if it does really exist.
But I’ve a few questions to the rumor,
First, if the old leaked image from the Pentax K-7 showing a 1.0 aperture on the top LCD was taken under a real condition (LENS-ON), why the ISO level was set to 1250 when the F-number was already 1.0 and at a speed of 1/8000S (MAX. SPEED)? Even in M mode seems that there should provide no ground for such a test?
Also, why would PENTAX produce a “D-FA” nowadays? Shouldn’t she concentrate on the production of DA Limited, DA Star & DA?
Mistral75, there’s nothing odd about it having a petal hood.
The old FA 35mm, 50mm and several others have petal hoods.
Even some of the new DAs like the 15mm f/4 have a petal hood of sorts.
