Doesn't look like 'new graphics stuff' so much as a revised new FS. But those behind it seem to have a rather conservative approach and I think they may have problems with this project - admirable as it is.
I started simming way before Bruce Artwick created what became MSFS. I remember playing with a university flight simulator my dad had in his faculty in the 1970's. Black screen and white dots for a runway.

. As well as being a real private pilot. I think the biggest problem for new sims now is that most people are moving away from traditional PC's for entertainment. Although there are still millions in existance in almost every country, very few kids are using them for their 'games'. So that new blood has been almost cut off for the hobby.
The beauty and key to success of the MSFS series was it's addon-ability --- and FREE. Which meant that it was possible for someone with a moderate amount of effort to create addons as a hobby and make them available to others. Plus the technogy was current for it's time.
It's a mistake to rely on the hard core enthusiasts, who will spend a lot of money on their sim, as a target audience. They are a tiny number. I'm certainly not one of them. I rarely see an aircraft or scenery where I can't get something just about as good (or better) for free. Combined with that, any new sim should be compatible with as many new technology platforms as possible -- MS/Google(Android)/Apple/Sony.
And I certainly wouldn't buy a sim where every addon came at a price and from prescribed sources rather than an open source worldwide community. That was the biggest failure of 'Flight'
