I made another update for my Vubu app (the first one in months) and I added new retina sized launch images to my project. I haven't submitted the update yet since it pushed my app size well over 50MB - the version that is on the app store right now is around 38MB. I'd like to keep it under 50. Does anyone know if you're required to include retina launch images now? Do you think it'll be rejected if I don't have them?
