Long story cut short, they're not forcing you, its a choice in the end, if you're not happy with what you have or where the company is heading, move on,cameras will change, photographers do not, as what Olympus said, in the future, DSLRs will be mirror-less, think about it, the first mirror-less cameras were from Panasonic, then Olympus, Samsung and Sony jumped in with their own NX and NEX series, rumors floating about Canon and Nikon making their own version, who's to say that they will phase out their DSLRs as well?
True that its pretty risky to do it this way, but eventually you'll have to do it. As said many times before,I'll repeat it again, shoot more and share, most people here are enthusiasts, E-5 is most definitely not a need for them or even a want, but the m4/3s and other mirror-less platforms are good in their own way, true that they're slow, but as I've said many times, technology improves very quickly, those in IT line will surely understand it, and eventually, the mirror-less cameras will catch up to the DSLRs in performance. So whatever the camera is, most important is that we still get the images we want.
