While I'm really looking forward to seeing exactly what the K7 will be like, I'm really excited about the idea of less expensive WR lenses.
I'm with Diego--a DA17-70 WR would be a beautiful thing. I'd be willing to replace my Sigma 17-70 with a 17-70 WR; in this case, it would be worth the extra cost of the Pentax version over the Sigma version. I'd also love to see them come out with a WR version of the DA55-300, especially if they modified the optics to allow for close-up on the long end like the Tamron and Sigma 70-300s.
I just love the prospect of having a fully sealed K20 & lens.
