Ot? .. digi-cam upgrade

I have a Pentax Optio 33 WR that is 'water resestant' fits in a shirt pocket
and takes good enough photos for most uses

but I'd like to have a similar type camera ( water proof, small, good
optics ) that has a higher pixel rating .. ie takes 'bigger' photos

I'm not interested in a bigger than pocket sized unit, or SLR or ... ...
( been there done all that photobug **** way back when, I once owned an 8x10
view, 4x5 view, 2 1/2 SLR and a couple 35mm SLRs + a Leica focal plane ...
not to mention a full darkroom ... NOW I just want a 'good camera' to take
digital pictures for hard copy printing at a decent size and high standard )


Suggestions? What's out there now that I should consider ?

as always
thanks in advance
