oppe98, it's my understanding that there is a show next week in Japan and it's possible that Pentax announces a new dSLR; if so, I guess it will be the K-r replacement.
And everybody looking at buying something wishes to know what's coming next; that does not only apply to cameras but also applies to cars, bikes, audio gear, etc But I doubt that current cameras will have the lifespan of the old SLR cameras; actually I'm quite sure it does not. My Minolta X700 is still going strong after nearly 30 years but I don't expect my K5 to live that long; with the rate of shooting that I do, the shutter should last 40 years, but I think that the electronics will die before that
