Raw formats running out of time?

QMy collection of digital cameras is as irrationally random as my film collection was. I shoot most on a couple of Pentax bodies, which offer me the ability to save raw files as .DNG. I have an Olympus E- 620 (which I am fond of) with some good lenses but my only foray into mirrorless was with Samsung, which pulled the plug just when the system was maturing. I do everything in Camera Raw and Photoshop but I convert the Samsung files into . DNG for fear that one morning I might wake up and find that Camera Raw has ditched the .SRW format. Should I be doing the same thing with the .ORF files since the system is also ‘dead’? Or is the old E-system .ORF the same as, or compatible with, the modern Olympus mirrorless system files? While the Adobe . DNG converter works fine, it is a rather tedious process if you have a lot of files. Horton Rogers

AThere is no indication that Adobe will abandon support for any older proprietary Camera Raw formats. Even if this happened, you would be able to convert to .DNG using the same .DNG conversion tools you currently use. In my experience, improvements in raw processing algorithms over the years mean very old raw files now produce better than ever image quality, rather like vintage wines improving with age.
