You know, it was kind of pointless to do a countdown for an iOS port. Other publishers just come out of the gate and say if they're going to have it ported to iOS. Not Square Enix, though.
Either way, the $20 price tag doesn't really bother me. People complain that it's too expensive for iOS. But it's a DS port, not a game you play for about five minutes while you wait on something like Angry Birds or Fruit Ninja. Those games are meant to be simple and are designed with a low price in mind. Unless you're Gameloft, who thinks it's okay to rip off other games since they beat other games to the iOS.
Besides, the game sells for no less than $20 - and that's for a used copy from Gamestop.
The World Ends With You on iOS has to be priced lower because it's on the same platform as Angry Birds? That would be like if people complained that the Xbox 360 or PlayStation 3 isn't the same price as a 3DS just because they're in the same store.
