There are a few reviews already around for Olympus' OM-D E-M1X camera, but this article goes deeper into the development of the camera and its advanced AI. Understand this clearly: you will NOT be able to simply load a firmware upgrade into a E-M1II body to get the improved performance because the E-M1X has an extra main processor (for total of 8 cores), and part of the design of the new body was the inclusion of a "heat-pipe" to distribute the resulting heat created by the extra processing. Likewise, the extra battery space is necessary because of the increased power requirement. It will be years before the "new technology" will trickle down to lower models.
