Yup. Usually I remember the rubric being about $30 back to the publisher on a $60-$70 title. MS/Sony each take a cut and so does the distributor (Steam, Wal-Mart, Best Buy, etc). Plus, as pointed out in comments below, there's also the fact that not all copies were sold at full price. So you're looking AT BEST at $120M in revenue, plus Irrational had TV ads and other large costs in addition to their staffing.
