It will probably bring us a KLAX scenery like never seen before... But the question I raise is: are those details really important for 95% of the users?
It's always difficult to launch into predictions about what's important for most users. In the end, it's the developer that decides (and take responsibility for his choices, with low sales if his choices are bad), according to his own style.
There are sceneries out there with falling leaves, barking dogs, 3d grass, animated people doing barbecues, you name it. Are those really needed for flying ? Surely not, but they are nice to look at, because of the always important concept of "suspension of disbelief", those details try to have you forget you are looking at a computer screen, if only for a minute.
And there's another aspect, we HAVE to move forward, if we just took sales data, our two bestselling sceneries (Zurich and JFK) didn't had anything of this, Zurich used a lot of FS9 code (before the 2.0 version) and JFK could use some improvement in textures sharpness too, but this didn't affected their sales.
But, if we kept applying the same tried and true methods, we wouldn't be moving forward, which is the sure recipe for demise, maybe not immediately, but before you know it, an iPhone/iPad could match the PC graphic quality, someone might do a flightsim based on it, and we'll end up with our pants down, still using late 2003-techniques...AND we'll be bored to death while doing it because, you should never forget that we do this only until is fun.
