As reported earlier, Canon should be announcing the EF 70-200mm f/4L IS II lens very soon. However, the replacement of the EOS-7D Mark II camera may come in early 2019. Here's my wish list for the EOS-7D Mark III camera.
It is not unusual for Canon to shift around the announcement date a few months here and there. I suspect they may have other priorities in mind, like getting the long overdue high end, full frame mirrorless camera to market.
