Ever since I got my iPhone 6 Plus on Tuesday, I have found myself not having to pull out my iPad 4 as often as it used to be. Right now, my iPad 4 is pretty much for movie viewing only where size does matter. Other than that, I can use my 6+ for everything that I used to do with my iPad. So to answer your question, I don't think the full size iPad will go away because movie viewing is still better on the full size iPad. But I can see the iPad Mini will be obsolete and go away very soon (kind of like the 32GB storage).
