According to the digicame-info, Sony will most likely announce a new Sony FE 20-70mm F4 G lens (SEL2070G). It might be announced in January/February, 2023!
Panasonic has a 20-60mm F3.5-5.6 for this kind of lens, but Sony seems to be a more versatile lens with F4 through and a longer telephoto end. However, with these specs, the size may be quite large.
