I have high hopes but one thing is a must the part count and its related bug should be removed from the game. I mean if your computer lets it players should be able to go beyond 400 or even 2000 part ships, stations colonies etc for me this is the most important thing I except from KSP 2.
Also if they can make docking little bit easier (not rendezvous thats kinda easy) will be great. I dont know you guys but I am having trouble in that area luckly we have mechjeb.
