I actually think that is a very smart Idea.
--for a couple of reasons --- We all remember how every major version of Aperture arrived broken and took a while to get sorted out, and the new OS may well require a new version of Aperture.
Also, looking back on the FCPx debacle, and not even being able to open legacy files with a new version is another good reason to be wary.
It's also difficult to gauge Apple's interest in Professional Still Photography. It certainly seems as though it is very low on the priority list. I am a very big fan of Aperture, but if I were a betting man.........
I run it on 2 machines a 17" 2.5ghz MBP 16gb ram running the latest version. And my production machine a now ancient Quad core 3.0ghz MacPro 16gb with updated graphics and SSD Boot which I have frozen at 10.6.8 and an earlier stable version of Aperture 3.x. Projects on that machine run to a thousand RAW files that ned to be edited and delivered weekly. It runs like a clock (if a bit slow at times)
But the machine cannot run Mavericks or newer. So at some point I'll have no choice.
The other thing the new OS may clarify is the whole 10bit color thing. I don't buy displays that often, and if that really is going to be the new standard, I'd rather buy into that.
7/9/14 I guess I should have been a betting man.........
Re the new MacPro: while the new MacPro has much to recommend it (especially for video) Inexplicably, Apple has (as I understand it) placed ALL the USB3 ports on a single buss, severely limiting throughput in multi device or RAID use. Something they did NOT do on a MBP (which is consequently much faster in multi drive applications)
This is even more important because although the new MPro has 6 TBolt ports, it only has 3 TBolt busses one of which is shared with the HDMI port. This is made worse because there is NO i/o expansion other than those 3 busses.
Lloyd Chambers outlines it here:http://macperformanceguide.com/MacPro2013-USB3-performance-limitations.html
So Apple's Fastest "most Professional" machine offers Apple's slowest USB3 performance, and there is apparently no way to fix it (short of a manufacturing change) because all the controllers are soldered in place. Disappointing.
It's also a bit dishonest, because who would think to ask if Apple's top of the line has an antiquated USB3 implantation?
