Why is that any good? Arena wasn't developed by EA and it didn't made it better.
As for CGI or Actors. If they can provide and ingame quality of lets say Crysis I don't realy care. When I land, step outside of my fighter, walk around the flightdeck and see people running around and I can interact with them and all without loading stuff and in the quality the Cryengine provides...well I could very well live with it.
The other thing is and that might be a point why EA should do it, is that real actors and probs and everything that goes with "real" costs a lot money most likely no other company has (and is holding he licens to Wing Commander).
So if you want real actors you better hope that EA is doing it or at least sponsoring the development.
Beside that with the new C&C, at least in my opinion, EA showed that they can revive an old classic game with the same strength and sadly weaknesses, of the original and add very nice, high quality (technical) cutscenes with real actors.
