Quote: I can say only one simply thing - K-5 and K-R will be better than new cameras from Nikon, Canon and Sony
In what ways? And for whom?
Not all cameras work for all photographers. The K7 is a great street camera, not so much for wildlife.
So making a blanket statement like that is kind of disingenuous.
And a camera is only as good as it's lens line up for some people. Canon and Nikon cannot touch the Limited's, but then Pentax has no current long glass.
Each photographer is going to have to weigh the strengths and weakness of the complete systems available, along with what might become available in the future, and how deeply they are invested in a line before they can say any camera is the "best" or better than any other camera, and that decision will be based on what THEY think is most important to them.
I've got high hopes for the new Pentax. Very high hopes. For me, the K7 wasn't the right camera, but from what's been posted, this new one seems very close. Unless there is a line at the door and I sleep late, I'll probably be one of the first to grab one from my local shop when they finally arrive. If that camera does what I need it to do for the type of photography I do, then for me it might be the best, but for someone else, who knows?
