The recently announced Canon 90D, Canon EOS M6 II, Sony a6100 and Sony a6600 are cameras that refine everything that is already a current technology but bundle it in a lower price package with great performance. However, it is clear from the spec sheets that high frame rates have stagnated for the past few years in these camera lines with a maximum of 120fps at 1080p.
Sure some of them offer full-time autofocus in slow motion modes and face tracking which in the case of Sony is so good that you may not even match it if you had the best focus puller in the business hired for your shoot. But the frame rate war seems to be left to other camera lines and brands. Panasonic, for example, offers up to 180fps in their new S1H camera which should be in theory the best Panasonic mirrorless camera ever made and it should also allow for outstanding quality in 1080p 180fps.
