I don't mind locked FOV as long as it's locked to something reasonable between 85 and 95. But you can bet your ass it's going to be locked at 60-70 even on PCs because of consoles and that's just another reason (first being lack of server files) to skip this otherwise great game completely.
I hope I'm wrong and the beta shows me a locked FOV of let's say 90, 90 is a good number for everyone.
If its at 90 im fine with it, but the higher the fov the more rendering that has to be done and the harder it is on systems, im betting as you are that it'll probably be 70ish to accomadate lower end systems.
