I think Pentax got into the DSLR market as early as they could. Once the six megapixel sensors became available and good enough for enthusiasts, Pentax had to wait for the price point to come down to where they had waiting customers.
Before then, DSLRs had started out at the $60,000 price point, then down to $20,000, then $15,000 (mainly Kodak DCS series), and they performed pretty poorly compared to a roll of 400 ISO film. But the electronic images were useful to journalists at the time, and newspapers bought them then, knowing they would quickly become obsolete, but if they got a couple years use from one, that was okay. And newspapers primarily had stocks of Canon or Nikon lenses, and pretty much never Pentax, Minolta, Olympus, or Contax.
So when Nikon and later Canon started making their own DSLRs at the $6,000 to $8,000 price level, Pentax and the others still had to wait. Unfortunately, they also watched Canon and Nikon work the bugs out of their systems and no doubt file a few patents, to go along with those of Kodak.
When the sensors grew to six megapixels, and it was possible to build a "prosumer" DSLR for $3,200 (and quickly dropped to $2,400), the timing was right for Pentax and Minolta (and Fuji) to make something for their loyal fans. The problem is they likely had to pay royalties to all the others for their technologies, as well as buying Sony's sensors. Minolta (later Konica-Minolta) gave up and threw in the towel. But we're fortunate that Pentax held in there. I think it's unfortunate that Canon and Nikon stole a march on the other companies because of their dominance in the newspaper/journalism market, where very expensive, and buggy cameras, could be test beds for future production, and then just tossed aside. Amateur enthusiasts just didn't have six grand to drop on a body with a four megapixel noisy sensor, knowing it would be eclipsed in 18 months.
