Be patient, it will be annouced tomorrow.
I'm very patient (usually). I just hadn't seen the rumour until today. But I've been looking for a small, lightweight combo for well over a year to complement my RX10iv which is a great do-it-all cam but not tiny (I appreciate it's nothing like a Nikon D3 with trinity lenses which I've carted around in the past).
If the rumour is right the small body and very small wide lens might be ideal for my use case. Plus the facility to add wider/longer/better lenses when required is very attractive.
So, yes, I can wait until tomorrow and won't hold my breath but I'm hoping it might be the end of my search (but I've been disappointed before - looking at you Canon Powershot V1 without an EVF) so we'll see.

For comparison, the X-T50 is also in that size class, though presumably a higher price class, with 40mp and IBIS. The m43 EM10 mark IV is that size range but lighter, with IBIS, EVF, D-pad and tilt screen, sensor smaller than APSC but bigger than your RX10vi. OM5 mark II is also on that size class but lighter, with IBIS, D-pad, EVF, side fold-out screen, but also weather-sealed, with more processing/AF functions than EM10.
