But srsly, why are people so sure its even 2013?
Except the obvious "it would be stupid of apple to postpone till 14"?
;D
I can think of plenty of reasons. They'll get destroyed in the market if they release Haswell MBPs next year, long after all of the competition launches. Believe it or not many people are cross-shopping Mac and Windows these days.
Mavericks was basically made for the Haswell rMBP. It's loaded with CPU usage optimizations designed to keep the machine at near-idle during day to day tasks (which is when Haswell's power efficiency improvements are most significant).
Releasing the refreshed rMBP with the new Mac Pro makes sense just in terms of a "Pro" line release theme.
All of the competitors are also releasing in October, which points to the entire delay being a simple matter of Haswell CPU supply.
The technology you'd expect for the next major overhaul of the platform isn't ready. IGZO displays, Broadwell's 30% power decrease at 100% load (allows for much faster CPUs in the same platform at the same or even lower power consumption/heat levels), OS X touch screen functionality (the base of which is launchpad, though this may not ever actually fully materialize), Maxwell NVidia GPUs... all of this stuff is largely impossible until around this time next year. Means there's not anything to be gained from waiting to launch.
The benchmarks, which I'm certain were not "leaked" so much as presented as a preview of the device/confirmation that it exists.
Honestly, the fact that Mavericks basically exists to improve the rMBP experience is the biggest clue. You don't design a major OS update around a product that doesn't exist.
The screen is what loses a lot of people.
Yep, huge disappointment even comparing to an iPad 2 and a 2010 MBP (17"). That shouldn't happen, even in the budget line; it should have been a decent quality 1440x900 panel instead of the so bad I didn't know they still made them like that TN panel (to clarify, I'm saying that it's bad even for a TN panel).
