Speaking with the Wall Street Journal, EA's Blake Jorgensen notes that the controversy surrounding the progression and micro-transaction systems in Star Wars Battlefront II was the reason it sold 9 million copies. As opposed to the projected 10 million. That being said EA are still planning on re-introducing microtransactions to the game. Eventually.
As to what form they will take is anyone's guess but you'd assume that the pay to win nature of the original model is getting reworked to be less, you know, disastrous.
Sales of Star Wars Battlefront II are also down compared to the original. The controversy surrounding the Loot Crates at launch saw EA pull all micro-transactions from the game, and as per previous word from EA and DICE the progression system as it stands today is being re-worked.
