The good news will be for potential K10D purchasers. With K20D coming up, K10D prices will go down.
So more photographers will discover how good is the K10D
Only possible surprises: the price-tag of the K200D compared with the K10D's one; the handling of SDM lenses and a short list of other technicalities.
Personally, I don't plan to switch from my current K10D: I'm very happy with it and the learning curve is worth taking more pictures with it.
I rather prefer to purchase improved lenses, as I did with the DA* 50-135mm, worth the price
