Releasing more offen will not bring new customer... I don't see the point, now they have solid basis as if you have bought all your apps books and movies on iTunes, switching I android or micosoft is bit more complicated... Honestly I bought iPhone 5 for speed but well I was happy with the 4... The only upgrade that will make me change is the battery improvement... My iPhone 5 is crap, it is not a mobile phone as it has a permanent charging cable on him...
