I've been having massive arguments online about iOS 8 device support. Its pretty obvious that it won't run on the iPhone 4.. but people claim there is no reason whatever for it to run on the iPad 2. I think there is.... eg. They sold it up to recently, it is probably the iPad with the greatest installed base, it runs iOS 7 fine(and iOS 8 probably won't be a big change) and they're still selling almost every other A5 device and thus support is pretty much guaranteed for them, so it is pretty much certain that they would have to support the iPad 2 if they support the others.
