When we get SSOCS, in a local region (like Port Olisar), what do you think our peak Player count will be either for ship combat or FPS combat?

It's a theoretical question, and it's hard to say but the probable answer is "as many as we can get". It's likely something that will be tested with the Evocati when the time comes, beginning with testing SSOCS with the current Player cap, and then expanding to see what happens. That said, they do have more sophisticated ways of testing this other than the Evocati, and they have "headless" client testing as well as Player testing (where headless clients are just clients that don't do anything). Either way, they'll be doing profiling around the Player cap, although SSOCS itself isn't likely to have a dramatic effect on it, unlike Server Meshing which will because they can shunt Players from Server to Server as needed.
