Handheld/tablet/smartphone market is one thing console is another.
Do you know how much it costs for a development kit on a console? Just curious, because you can make money on PC for 0$, console is a different story (try 100k$+).
So do you think Blizzard can't make money off of console game sales?
After the reputation that Diablo 3 got? probably a very small revenue, nonetheless it'll still sell, nowhere near close to 12 million though i'd bet.
