that is actually not true anymore with the wiiu. over the course of 2013 the average wiiu owner bought 5 to 10 games for it which is a very high software attachment rate meaning that there would be a high chance that the majoraty wiiu owners (most of which are in their mid 20s or 30s) are likely to buy the game. so lets say porting the game costs between 5 and 10 million$ and lets say that at least two thirds of the wiiu owners (about 4 million people) instantly buy the game. that would be a revenue of 4.000.000 times 60$ which far exceeds that estimated porting cost but that is just me speculating the only way to know for real is doing it and it would be foolish for activision to let that opportunity pass.
