How much Revenue does the Fable 2 DLC have to generate to become profitable

[Seece]

I took the minimum number of people who downloaded the DLC (I have 50/53 achievements on my gamercard.net and 1039 people have 51,52,or 53 achievements on Fable 2 which means they would have had to have DL the DLC)

Bare in mind 1000 is the minimum

 

So I did the math and lets say all those points spent on the DLC were from the US (Probably the cheapest place to get points)

so yeah it comes out at $10,000 so far.

5000MP = $62.50

 

I'm pretty sure more people have downloaded the DLC so about how many downloaded (of revenue) does the DLC have to make to become profitable?
