I would also like to see DX11 support (please no 10!!)
In my opinion a gamestudio IDE would be freakin' awesome. Not like Visual Studio but more for gamestudio. Like combining a coding environment with a level editor, model editor and interactive shader editor (change code -> see results)

I don't want a change of the programming language, i really like lite-c. But also a better support for other languages would be great. Or a good scripting support like Javascript, Lua, ...
