According to this article at IGN
"Riccitiello admitted that while EA did "absolutely nothing" to market the PS3 version, the digital copy captured a double-digit percent of total sales for Mass Effect 2 on PS3. EA has not revealed a specific sales number since launch, but Riccitiello said it was "meaningful.""

Whatever the actual value is, we know it's at least 10%, which is at least 26k sales through digital downloads, using VGChartz number for physical sales of ME2.
That could be more than $1 000 000 for EA from digital sales alone.
