EA is satisfied with the sales that Titanfall has sold so far, but specific numbers have not been revealed yet.
EA’s CEO Andrew Wilson told Eurogamer that Titanfall exceeded their sales expectations. It’s still weird how EA have not given a definite figure on the game’s sales though.
EA has confirmed though Titanfall is the best selling game on Xbox One right now. Somewhere along the way, it managed to beat Call of Duty: Ghosts.
EA has chosen not to comment on a sequel yet, but chances of another game look very likely.
