Of those, XCOM is the only game that exists. Star Citizen, Project Infinity, Torment Tides and Wasteland 2 are all Kickstarter-funded games in development. Kerbal is available, but not finished, and as you say, not really a game.
Sure, there are some interesting games in development (I'd add the Elite remake and Double Fine's untitled adventure game to the list), but who knows what they will be like. We don't know if they will be "quality".
