As an XE1 owner who has been waiting for the XE3, I was very disappointed in the news of the XE2s, which is a 2 year old camera with a larger grip and new firmware. If I were going to upgrade now, there's no compelling reason why I (and anyone else) shouldn't just buy an XE2 for less money and upgrade the firmware. I don't think the XE2s will sell very well.
I don't enjoy the shooting experience with a center viewfinder at all, so no XT series for me, And I'm not buying an XPro2 as I dont need an OVF, and it's too big and heavy for my needs which defeats the point of going mirrorless, IMO.
If we have to buy the XE2s to ever see and XE3, then we will never see an XE3 and Fuji will likely lose me as a customer.
