The short answer is NO. The answer could be yes to you depending on your needs and shooting preference. What we know currently from the recent announcement of the new GH5s (Which is available for pre-order here.) is that the new camera lacks the IBIS. Which is the amazing in-camera stabilization which the GH5 and the G9 have. A lot of hobbyists and professionals around the internet have been whining about this feature not being carried over. Which, I might add, is a really nice feature... but I for one can survive without it. Considering what DSLRs offered in the recent past, the GH4/GH5/GH5s as well as the A7S line from Sony have come a long way in the terms of light-weight, feature packed cameras for video. I have yet to get my hands on a Panasonic GH5s, but am excited to try it out. With the new sensor, this sounds like a vast improvement for lower lit situations versus the previous models.
