iPhone rumors are like flies at a summer picnic: they’re nearly unstoppable. Collected in one batch are all the iPhone 5S/6 rumors CNET has reported so far, with some commentary on where these rumors came from.

We always have long wish lists for newer features and further redesigns, but the bottom line is this: nobody knows exactly what we’ll get until Tim Cook reveals it on stage later this year.

That said, we’ve got plenty of educated guesses. With that caveat firmly in place:

Odds are strong that the immediate successor to the iPhone 5 will debut in the summer to autumn time frame (June to October). The release will all but certainly coincide with the availability of iOS 7. Moreover, if it follows Apple’s previous history, the new iPhone will have the same design but with tweaked innards, in the spirit of the iPhone 4S and 3GS.

Beyond those obvious notes, the areas that seem most ripe for updating on the “iPhone 5S” would be the resolution of the cameras. And now that there’s a 128GB iPad, maybe there will finally be a 128GB iPhone option, too.

Everything else is pretty much a crapshoot. A bigger screen? CEO Tim Cook says no — but saying one thing and doing the opposite would hardly be a first for Apple. Beyond a screen size change, though, Apple could also go with a different technology — say, Igzo or OLED.

There are plenty of other unknowns, too. Will there be another iPhone that debuts before a fall model? Could the iPhone product line split into several differently sized models? Will an affordable “new” budget-line iPhone emerge? Will Apple finally add NFC to the iPhone, as part of a new mobile payments scheme? Anything could happen. Or not.

As more rumors emerge, they’ll be added here.
