To the people saying the interface can be fixed by modders, I hate to break it to you but without an SDK release this won't happen.
Why? Because without source files, all you can do is basic stuff like replace models, make new maps, replace sounds and do basic scripting. You can't redesign menus and things that require coding.
So Pandemic HAS to fix those things if you want to fix them at all. Or at least provide the modding tools that will let us fix them. Otherwise you won't see any (legal) mods that fix the menus and netcode for example.
