Some of my pie-in-the-sky wishlist for Elite over the next five years, tech-wise:
-Expand instances to be system-based vs planet/POI based
-Until the above happens, continue to improve on load times when loading instances (dropping out of cruise, particularly on planets/based)
-Improved streaming and LOD
-Horizontal displayment in Stellar Forge and/or wide variety of crafted models that are integrated intelligently into procgen
-Improving the quality and variety of shaders (which they seem to be doing)
EDIT: Aaaah, not even gonna get into CitizenCon stuff.
All that stuff (except for horizontal displacement) is probably on their "list" but who knows when Frontier will actually get around to it.
