I thought for a while that Apple's frameworks, Cocos2D, OpenGL ES, can all work fine with The New iPad's Retina display, until I saw this post: http://www.cocos2d-iphone.org/archives/1845
So looks like for now, any coding that has to use Cocos2D to release a version on the App Store for current iOS devices has to use the Beta version? Will that risk our own iOS project because a non-stable version of framework needs to be used? Then maybe only Apple's frameworks and OpenGL ES have stable versions of frameworks that work on The New iPad.
But hopefully when the Cocos2D becomes stable with The New iPad, it won't need to upgrade for higher resolution for a few years because Retina is already at a quite high resolution.
