The Iphone 6???

I'm a current iPhone 5s user. Just curious on who's going to stay with what they have 4-5s or who's going to get the iPhone 6. Also is their anyone that's switching back to the iPhone from android. Due to the upcoming iPhone having a larger screen size now? It also would be nice to see sometime of sd storage but I'm guessing that would never happen. Due to apple and how they operate with iTunes and security issues. Also the iPhone is made to just work with no headaches involved.
