I agree, the new Pentax looks promising, especially because of the lens. Canon took their sweet time getting 28mm into the G-series, so I suppose they could relent on some other models as well. Someday.
For now, based on design I'm most impressed with Pentax and Ricoh. There may be hope for future Olys, now that they've released their first camera with SD rather than an xD card. I'd love to see Nikon waterproof the P6000 while fixing some of its quirks (no idea if this would be possible). The feature set (including GPS tagging and OVF) would be irresistible.
