Camera upgrade

Hi folks,
I am thinking of upgrading my camera from the Olympus OMD-EM10 mark 1 to the new OMD-EM5 mark 3 and there are some very good deals around at the moment. I was hoping to get some hands on at the photography show earlier in the year but of course that didn't happen. My trusty EM10 is no longer supported by Olympus and has not had an upgrade since 2016 and amongst other things it does not talk to my phone for remote shooting, I can control the shutter but am unable to see what the camera is seeing. The weather sealing of the new camera along with focus stacking etc are very tempting. My question is the lenses on offer are the 14-150mm f4-5.6, 12-40mm f2.8 pro and the 12-200mm f3.5-6.3 travel zoom. Currently there is the offer of a free 45mm f1.8 portrait lens as an extra plus a spare battery. My preferred genres are landscape, street and macro, apart from the kit lenses which came with the camera I also have the 30mm macro and the 17mm f2.8 prime. I am tempted by the 12-40mm pro which I think will be good for landscape and street, and then look for a decent 2nd hand 75-300mm f4.8-6.7 for wildlife albeit in good lighting only, the 300mm pro sadly being way out of my price range. Has anyone any thoughts or advice?
