Have you prepped any assests for this yet? I'm thinking it may lead to the death of universal apps. maybe..
In WARP gce I of course have retina images (iPhone/iPod) and they add about 12-13MB's to the overall app size. I just did a quick check in preparing iPad retina images and I'll be lucky to squeeze them into another 22MB!
That makes my 45MB app grow to nearly 70MB!
