Im pretty sure apple will announce the 4.7 inch and 5.5 version in september during their long awaited keynote. But the 5.5 is an absolute must. First let me say if iOS was able to run on other devices (natively) then I would have bought a galaxy note 3 a long time ago and ran iOS on it. The 4.7 version is not an exciting prospect, one must ask what can a diagonal enlargement of 0.7 inch provide to the end user? Ultimately we will continue using facebook, snapchat, whatsapp etc. I will be buying a new iPhone soon but I cannot justify 800-900£ of expense on a slightly bigger iPhone, it simply is not worth it. However the 5.5 certainly will be. Its been embarrassing for so long, pulling out a little 4 inch phone when everyone else has got 5-5.7 inch phones. Credit to apple, they find a way of making their product desirable after they update the hardware. I really like the macbook air and the pro but im a windows user so I cant buy it unless windows is PROPERLY supported on macs. However iphone sales will start slowing down. It will get to a point like PCs have where there is enough processing power to do the tasks everyone needs to do, like whatsapp snapchat facebook etc and there is little benefit to be had from additional horsepower unless you are a gamer. Funny how these chinese manufacturers are releasing quadcore 5 inch phones at 10% of the price of say galaxy s5. The 5.5 inch will be the true flagship device. The 4.7 will always be seen as inferior.
