How can you state there are two camps of people, then say they would buy both? Kind of contradictory, no?
I certainly would NOT buy the game rich in online features. I've played online maybe 3 times and hated it to the point where it's discouraged me from playing other games online.
Like I said, your theory is great, but it will NEVER.never.NEVER happen. EA is all about the benjamins, and producing two games for the same amount of customers will NOT happen.
