Good summary!
Totally agree about Skylake, I'd be very surprised and disappointed if Apple doesn't pull through on that one. To all the people saying there's not enough inventory/production on skylake chips yet, it's like you're forgetting who Apple is. They're probably the reason there's a shortage
Good point about no code being found about 3D/force touch trackpads. I can see that going either way, it's pretty much a given - just a matter of when. If force touch doesn't come on Tuesday, surely it couldn't be further away than with an early 2016 refresh. Which begs the question - what are the differences going to be between this October model and next years if we get skylake and TB3 now? There's also the option they just release the new Magic Mouse/trackpads as standalone accessories in the next few months, maybe to coincide with the release of Apple Pencil? Though that wouldn't make them look too good if they just shipped a refresh with older mouse tech. My bet is we'll see it this update.
Ughhh just wanna know already haha! Bring on Tuesday! Regardless I'll be buying this update. Been waiting too long
