Advice please on G80 or G90 and 24-140 lens

Thanks everyone for your advice.  My macro is probably 105mm, it has been a long time since I looked at it.  I hope that I can find an adapter for it.

I have looked at several G90 and 14-140 offers and none of them say Mk11 or give serial numbers which is annoying.   So I assume that it is probably Mk1.  On Amazon Mk1 is £479 and Mk11 £449 on some sites and £620 on others as is Wex £620.

Is the 14-140 kit lens the same as separate lens or is it a special cheap one made for the kit, anyone know?

If it is same as sold separately then even Mk1 means the camera would only then be £550, which is a good price considering G85 is £499 cheapest at them moment.

I have read several reviews, and  G90 is alot newer so presumably better.  Any reasons for one over the other?  Reviews said not alot of difference, but given price at moment of G90 14-140 then price difference not an issue.

The review said the grip is different than the G80, I found the G80 ok, is the G90 much different?

Of course I would like it cheaper but the G80 has taken a long time to drop in price and Panasonic don't seem to have done any significant promotions ( that I have seen) since Nov 2018 when it had cashback of £200 for a week.  And I missed it due to dithering.

Do  you think there will be any significant price drops or promotions soon? Of course this has dropped from £1200-1300 to £999 and may go back up soon.

My Fz150 does quite nice pics on quite close subjects, so this will really be for more distant, but not too distant as will only 100-300 not 100-400 subjects, and not prime lenses.  So I am still really trying to justify why I need a SLR again at this price.

Thanks
