I don't believe the game was in development long enough to have a HUGE cost of creation.
I put development time at around 3 years, which probably puts the cost somewhere between 5 and 10 million max.
And Stratos is right about reusable materials. Assets will be reused across all future games in the series, including Extraction and any other games made down the road.
There really is no arguing whether or not this game was successful, it WAS. Redwood Shores made it and, to my knowlege, they have seen VERY FEW of the layoffs EA has been throwing around across their entire organization. That's saying something right there.
