Remember when so called analysts clamoured for a smaller size iPad? Now they do the same for a bigger screen iPhone. They did it before the iPhone 5. If Apple chose to not do it and clamouring the start of irrelevancy for Apple is a bit of a stretch.
That being said, personally I seriously think that we’ll see a bigger screen iPhone (aka the iPhone 6), a bigger screen iPad (aka iPad pro) and a very small screen device (aka iWatch). But I don’t expect a TV screen though.
