I don't expect to see it at WWDC, but I would love for them to release an iPhone 6 family. One with the standard 4" screen, an iPhone 6+ with a ~5" screen and a 6C in cost-reduced form.
Additionally, I'd like to see BASE capacity at 32GB, with 64GB and 128GB options in increments of $50.
Given that we're now recording in HD, shooting pics in 8MP and installing more apps than ever, 32GB needs to be the standard. We're talking about $5 worth of flash memory, wholesale (TOPS). And doubling capacity in the age of cheap SSDs should not happen in $100 increments. That's just pure greed.
That is, unless, Apple just wants to cede more ground to Samsung. Something clearly needs to change. I don't want to go back to Android, but I have to say that with my eyes starting to degrade, those larger screens are looking more and more appealing.
