Like computers, it's pretty hard to predict what may be antiquated in a few years. I haven't seen a floppy drive in years. I bought my first screw-mount lenses in the late 60's, confident that they would be around a long time. Then Pentax went to bayonet. I switched to Nikon, figuring at least they would keep the same mount. They didn't. Gaa! I fortunately didn't switch to Miranda, Konica, or Minolta.
My concern about 4/3 is that it seems that only Olympus is currently sticking with it, but I suspect that they will soon go to m4/3 completely. WordStar dominated word processing in 1984, so that's what I bought. Gaa! Used it with a CPM card in my Apple IIe. Gaa! Switched to a PC and WordPerfect, the dominant word processor in the late 1980's. Gaa! Nothing is sacred. Evolution happens.
