I'm in a similar situation! I still use my trusty GF1 which is by far the best camera I have owned and I wanted to eventually upgrade and bring my lenses that I accumulated over the years with me. Olympus had a solid m43 lineup back when I last checked. I was always a little frustrated how some vendors just started their own mirrorless, fragmenting the business. Its a shame and I am afraid to what will happen with m43.. its a shame if it goes, it is still a world better than cell phone cameras and it is so much more convenient than full frames.
