The WP10 is a new model that I hadn't heard about.

WP10 may have been the name in development, but when I looked for it, the only
thing I find is W10. They seem to be the same camera based on what dpreview
and the Pentax web sites (Canada, US and Japan) have to say.

W10 and Olympus 720 SW are both JIS8 (1.5m depth for 30min). The 720 is listed
as shockproof and is 7.1Mp, while the W10 is not and is "only" 6 Mp (only... I'm
still using a 2Mp camera). I know someone with a 720 and shockproof + metal
body or not, it's so small and light it doesn't _feel_ like it would handle
paddling. That's obviously a bad bias based on the naive sensation that heavy
and bulky = tough. The 720 photos are good. The Pentax W10 does get a better
rating on dpreview, but those are buyer ratings, so take them with a grain of
salt. If I had to buy tomorrow, it would be a tossup between the two. I'd
probably fuss and worry and then think I bought the wrong one - at this time,
they look that close to me. MHO, of course.
