Can you explain the f/1.0 in the LCD display image that was leaked when details of the K7 were emerging? Or have you thought that Pentax is possibly shifting to FF, hence the removal of the DA 30 and the sudden appearance of a prestige lens such as the DFA 50?
Wait. The f/1.0 is explanable simply as the firmware debugger program displaying the maximum default ranges.
The last question is a red herring. The "sudden appearance of a prestige lens such as the DFA 50"
has not happened; the legitimacy of this very claim is what is being debated, and so it is not yet a fact that needs explanation.
The case for the picture being a fake is strong. The engineering difficulties of producing an f/1.0 lens on the K mount have been described. The costs are almost beyond imagination, and the place of such a lens in the Pentax line-up is hard to figure.
In short, none of the questions you pose here pertains to the issue. A faked roadmap image proclaiming a virtually impossible lens, probably inspired by the default debugger screen of the K7 LCD firmware…
…all the same, I hope I"m wrong in my skepticism!
