Just my 4 pennorth, as the owner of 5 DSLR`s (3 Sony, a *ist DL2 and a GX10) I will continue to use them and their lenses until they stop - or I do, and not replace them. I wonder how many of us feel the same way? Use what we have until it stops working, then switch to the compact or retire and find a new hobby, though at 76, choice is limited, maybe just go for the walk and look at the scenery, and not bother trying to record it. Changing the mount to something un-useable by older cameras is in my view short-sighted, and will merely result in the easiest of commercial activities, the lost sale!
Just my thoughjts, and probably of no interest to the powers that be at Ricoh, but heigh-ho

Been there done that with memory card. Spent 3 hours at Woodcote Steam Rally, loads of photos, only to discover card flap open and no card! Frantic search in grassy field trying to remember where I`d stood, gave up, went home to find memory card still in computer!
I`d also like to know who goes around changing all my photos. I take what I think are good shots only to get home and find they`ve changed when I put them on the computer, and are not what I took!

Methinks Spring is definitely here. I went to Harcourt Arboretum at Nuneham Courtenay last week to look at trees and the Daffs were all out, thousands of them. Sorry no photos as I`m still getting used to my Pentax K10D clone, a Samsung GX10. Different to my Sony cameras, but I`ll get there. - bought as I wanted to try something different, and the GX10 + 2 lenses was less than a K10D body, mmm.
