I'm using FS 2008 and I've got too much detailed scenery now
Perhaps you mean FSX, which came out in late 2005 -- it was the last version made, so far.

As to FS "coming back," it appears that it'll only run on X-Box or Windows 10, and will be a subscription model, rather than a one time purchase. Since I'm still on Win 7 I couldn't use it, and in any case I'll not pay for subscription software.

But maybe, just maybe it'll be better than the Microsoft Flight they tried a few years ago.
