But even those can't shake a stick at the K-7/5 weathersealing. I've shot in wet, constantly splashing conditions and watched D3's go down around while not getting splashed nearly as much as my K-5 was. THe K-5 is virtually waterproof. If Pentax/Ricoh turns their back on the weathersealing, it would be a terrible move. The K-5 body is amazing, and just need some beefier functionality, and a way better marketing push. Ricoh doesn't need to reinvent the wheel, they just need to funnel lots of money into marketing and R&D to make their bodies competitive in AF and Video.
