Oh no. This is a huge blow to the MFT form factor (which is supported mostly by Olympus and Panasonic), which I personally love.
Agreed though I think this could go either way. Either Panasonic steps up their line up and becomes the sole M43 manufacturer or it fizzles out. I really think the M43 ecosystem is severely underrated in a world where cameras are pitched solely on specs. The body to lens ratio is so great on the M43 lineup and I absolutely love my GX85 for just that reason. For most consumers or even prosumers who don't make a living…
I have an equivalent lens for my Nikon J5 (so I'm in no rush to pick up the 9-18 - or I should say -was- in no rush prior to the Oly announcement), and it's the lens I use the most during the day when traveling. When I travel, I usually bring my J5 with the wide zoom and my GM5 with a pancakey lens (switching cameras is easier than lenses, imo) plus a lightweight long zoom.
