Seeing as COD is a highly-polished game, I don't think we ever need to worry about ED turning into it.
It's also the same shallow thing year after year, a short campaign with some maps to allow some pretend soldiers to shoot each other online. But it's popular because people like that sort of thing. Others, though, prefer to play something a bit different.
ED was never designed with PvP in mind. In fact, in an early interview, Braben said that open was meant to be cooperative.
