One of the most popular and affordable vlog cameras is the Canon EOS M series, specifically the EOS M50 Mark I and M50 Mark II. Since Canon had discontinued it, that leaves Sony. So I can see the Panasonic G100 Mark II as its EOS replacement. Since Panasonic is very strong in video, it's only natural to take the place of Canon in that market segment.
Despite the G100 being a capable camera, the main reason it didn't sell well is because it WAS competing against the Canon EOS M50 Mark II, which is still the best selling consumer budget vlog kit despite having similar specs, except maybe the Canon having a 24MP APS-C sensor and the G100 with its 20MP MFT sensor. The consumer only sees size, so there is no contest. I also think the G100 came out slightly more expensive. Both cameras do not have built-in IBIS. It was never a problem selling the M50 Mark II without IBIS.
To be competitive, the new G100 Mark II needs to have a 25MP sensor with Phase Detect and needs to have the dual boost DR feature of the G9 Mark II to take the Canon EOS M50 Mark II's place in the market. At least, get Canon people to upgrade to the G100 Mark II, rather than to the R Series cameras, which is bigger. Since most Lumix lenses are stabilized, it makes sense to produce a G100 Mark II.
The second camera, however, could probably be the S1 Mark II with phase detect, a hi-res version of the S5 Mark II. The GH7 seemed to be too soon to be released, but who knows.
