I think that Mu said you'll get that, he did a major overhaul and they are shipping some of that with .22 and some with .23. As for me, I want to see more career mode development, specifically missions and money. I would love to see a system where at any given time you have 3-6 mission offers on the table, each with a different cash reward. As you complete them new ones would become available (e.g. Good job landing a probe on the Mun, now put Kerbal on it!). This would preserve the choice in KSP, letting players focus on what they find fun (Interplanetary travel, Mun bases, space stations, exploring Kerbin, etc.). All of these missions would give tangential opportunities for science, so your flights would really start to feel goal-oriented and science wouldn't feel like science for science's sake.
