EA give up an opportunity to sell content!?!?
That's what they do - remember the old micro-transactions mess? EA is the King of "Anything for a Buck." For years they would sell a game for $60 at launch and have a $30+ DLC pack you could also get. EA will do anything they can to get as much money as they can from consumers.
I even suggested they release all packs with a 30-day trial where you can sample the pack before you buy it and if you don't buy it, they just disable it from your account. Then I realized, if I had the chance to try the packs they've released over the years before I bought them, I wouldn't have most of them.
