Let’s quote the Head of MSFS, Jorg Neumann (Sep 29th. 2021):
Weather for us is a Big Deal. It is something we are heavily, heavily investing in. I think with Meteoblue we have a great partner. Late this year you will get this first Update (remark: SU7), we’re planning on another which will be really awesome when it happens. It will probably be in 2022, it could be as late as 2023. Weather is one of those things. It’s where planes live, it’s got to be awesome. We will get it as good as you can get it. That is really the goal.
Obviously the goals have changed, as a “safe assumption that the weather system will be among the items seeing improvements in SU13” is all there is to expect. That’s far from AWESOME.
There’s silence on this mysterious further Update ever since.
To Jorg Neumann:
If there has been a change in priorities, please communicate it openly! We then sure all have better things to do than to waste our time for a lost cause.
