Matric 300 anyone?

I’ve been investigating various options for the best drone that can be used for commercial drone operations (mapping, surveying, inspections) as well as decent photography and settled on the DJI M210 RTK V2 with Z7, XT2 and Z30 cameras. Having decided that, and coming close to purchase I’ve started reading rumours of a m300 series soon to launch.

Is anyone able to substantiate these rumours or add any further details? I’m reluctant to invest heavily in reasonably exoensive kit that could soon become out of date. Perhaps there’s something better than the M Series anyway? (the M600 is too large)
