@Black-Square OMG, you have no idea how happy that makes me.
I was toying with the idea of upscaling the interior textures or something, but when I really look at it, even by today's standards playing at 4K it's still a great interior and there's really nothing that doesn't look good. The aircraft is such a joy to fly and the combination of GTN 750 with its many modern features, with leaning the mixture, working climate controls etc. really makes it fun even during long flights without a huge learning curve. With an updated G3X it'll be a whole new level. As my kids would say, this aircraft is "OP" and I sometimes wonder if it's even possible to make one that fast that in real life, with a weather radar to boot, but I'm willing to suspend my disbelief. ;)
The only other aircraft that can top it for me is the Starship, IMO the most beautiful aircraft ever made. I'm first in line to buy it and it'll be nice to be able to use twin throttles, but the Velocity is still needed for the smallest airfields. Super happy you're going to update it, and I hope it continues to sell for you to justify the effort.
