Will there be any kind of level-up experience or skill system in Star Citizen?

No, the idea is that you're using your own skills rather than, oh, you're a level 2 Hornet pilot, level 3 Hornet pilot. You have to actually be good at space combat or making deals. It's not an artificial leveling system.

We want player skill informed by your item choice and loadout and your circumstance, and not the other way around.

And that involves us as well. When we start doing balancing... like I think I mentioned a while ago, our mass system is completely haphazard. So we need to actually refactor that and have more realistic mass values for all ships, by determining their materials and what they would actually be, so that... flight characteristics, it affects everything. So that's one system we need to revisit when we're doing these balance changes.
