Despite the sarcastic tone of other parts of the post, this is what I actually believe. Counting out the non-technical crew and the management, there can't be more than 3-4 IT guys, especially since a lot of the graphics works are outsourced and a large part of the code is reused - that's why they often add features nobody asked for ("Hey, look what I've found in the public cryengine repository, and it's free, lets add it!") and struggle to implement/fix things that are really wanted.
After all, the game that is often mentioned in one breath with EU, Afterworld, is made and maintained by 3 students part time (which explains why they'll never become a true RCE or come out of beta - they don't even have a registered firm or pay taxes).
