I'm fully convinced that it would have been beneficial for EA to just pull the plug on that port. No way they are making any money on that one.
Makes you think about almost any future 3rd party game getting 2nd and 3rd thoughts before committing.
You have to consider that there was the $30 deal for it on their site and it's available online on the eShop and we don't know about those sales either. I'm sure in total it's sold more than 10k.
Still, the Wii U version of Need for Speed didn't allow for players to get DLC. In a car game, that's pretty crappy.
