Seems like a big stretch for Apple to release a .6”. Bigger model same specs as the 15” and not drop the 15” all together. that’s all I assume is happening. Slight design tweaks but I doubt this thing will be what everyone thinks it will be. A higher end MacBook Pro. There’s just specs they would make it assume that so far.
Apple has not gotten every ounce of investment back out of the current chassis and I think that most here in this forum are going to be livid once this thing is released. I can actually see Apple adding a hair more gasket lip to the display housing to give the scissors mechanism just a touch more room to set correctly while closed. I also think this mechanism is going to be more or less a "thin" butterflied version of the scissors and may fit just fine inside the chassis as-is, with suitably shallow travel. I actually don't expect any additional ports at all. I expect the Touch Bar, I expect the sound jack on the right side, I expect the only thing that changes to bee the display. I don't even expect the GPUs to be different.
The display is probably some sort of cut down take on the Pro Display XDR technology and that will be the major driver that pushes up the cost. It will be gorgeous, but will it be worth it?
I hope I am wrong. Otherwise, the only USP seems to be a slightly larger display to raise the price.
