a while ago there was a voting for most wanted features, multiplayer and Modularity where toprequests, i still think multiplayer came to soon, or rather modularity should been done before multiplayer, thing was, multiplayer could be done in current engine/editor and modularity not, then multiplayer was done, the only choice left was starting on a updated version of the engine, that can bring improvements to modularity, better search, , and pretty much everything that current editor was limiting, and also, c2 c3 its just a number... its just a bigger update than anything before, lots of software do it.
