I know it's not much but...
Today, a game released for Windows Phone 8 before Android and iOS, Gravity Guy 2. Considering that it's not a first party MS title or a Xbox Live title and that Miniclip's portfolio on Windows Phone (7 or 8) is nothing compared to it's portfolio on iOS, I think it's cool that MiniClip is giving the comparative little guy first crack.
Of course in an ideal world, new apps will launch on all platforms at the same time (or maybe Android first and everything else later :-D). In reality, apps launch on iOS first then gets ported over to other platforms more often then not. While I don't think that this will buck that trend much, I wouldn't mind more app parity across all platforms. The difference in hardware/how well the OS optimizes the HW has decreased considerably as of late.
