In a new report out today, KGI’s Mingchi Kuo updated his previous predictions for the iPhone 5S due for announcement on September 10th. Notably, he expects:

(1) the new A7, ARMv8 based AP (application processor), featuring a 1GB LPDDR3 RAM chip; (2) a sapphire home button with fingerprint  sensor; (3) main camera unchanged with 8MP, but featuring a larger F2.0 aperture with dual flash lights; (4) new option for golden casing; and (5) new option for 128GB storage.

We’ve heard the Sapphire fingerprint reading home button previously from Kuo and the A7 is the natural successor to the A6 and will likely be a 64-bit processor. The 1GB RAM seems in line with previous predictions but that 1GB of RAM will be faster according to Kuo:

We reckon A7 will upgrade memory bandwidth spec to LPDDR3 from LPDDR2 adapted by A6, in an effort to improve system performance. Since Apple is in charge of both hardware  and OS design, it is capable of minimalizing memory capacity at an optimized state. Therefore, A7’s RAM will likely be unchanged at 1GB.

However, the Gold option is something that has been only heard of in more sketchy rumors until now. Additionally, we discussed the 128GB option in our roundtable quite a bit yesterday. The iPad got a 128GB option this spring and the option on the iPhone would be a big differentiator for power users.

We’ve also heard the upgrade on the camera would include an F2.0 aperture with dual flashes but have heard a variety of megapixel options including 12 and 13. As with previous ‘S’ models, this one would be able to take dramatically better pictures, especially in low light situations.

Kuo doesn’t believe that there will be NFC capabilities in the iPhone 5S.

All told, Kuo expects Apple to sell 35M iPhone 5S units in 2013 (not including previous models and the lower cost iPhone 5C) as long as sapphire fingerprint reader manufacturers can keep up with demand.

Kuo’s record on parts predictions is good (timing notwithstanding) and these predictions should be taken seriously.

The hacked apart cable costs as much as a Roku because it has the same kind of horsepower

The fine software developers over at Panic are working on some new AV software, and they are investigating Apple’s new-ish Lightning Digital AV Adapter. What they found is that unlike the earlier 30-pin module, the Lightning adapter doesn’t carry a native 1080p signal. In fact, when mirroring, Apple says the optimum resolution is 1,600-by-900, and, when that signal is shown on a 1080p display, it is likely up-converted, showing artifacts consistent with streaming and uncompressing video data

What’s more interesting is that they split open the cable and found a full ARM processor with 256MB of RAM to process video signals inside the adapter cable. We knew way back in September that the 8-pin adapter wouldn’t carry video natively, but Apple was able to build a cable. How? Panic thinks that it is actually streaming an AirPlay network signal through the cable, and the ARM processor is decoding it.

Why would Apple do this? It’s likely Apple wants to move people to AirPlay wireless streaming to Apple TV, so this is just a stopgap solution. Rather than making a larger Lightning cable, it sacrificed on wired video-out quality and HDMI (And VGA?) cable costs.

Update: Our friends at Braeburn and an anonymous Apple Engineer sent along their takes on the situation below:
