Based on nothing but conjecture and wishful thinking:
1. Hexacore Xeons were rumored to be available at the end of June.
They have been available. The issue is more so are they shipping in sufficient volume to guarantee Apple as steady stream of the products with the deliver times they want. It is one thing to "announce" a product and take orders which are always follow with "ships in 5-10 days" and another when want that to say "ships in 24 hours" on a consistent basis.
It also isn't the hexcore that are blatantly missing from Intel's lineup. The "next gen", Westmere being shipped in limited fashion are
not all hexcores. There is a mix of quad and hex in the line-up. Intel has not announced quad 3600 series replacements for the 3520 and 3540 (used in the low and mid versions of the single processor package Mac Pros ).
Compare the current line up for the 3600

to the 5600
http://ark.intel.com/ProductCollection.aspx?series=47915
The first is a very odd looking duck. A whole series that consists of just a lone solitary offering. That doesn't look incomplete ?
If Intel comes out and says they are flushing out the 3600 line up and are fully up to speed on 32nm shipments and then Apple doesn't ship, then that would be strange. Right now, it is not so strange.
2. Judging from WWDC they wan't iPhone front and center for now a
No. It is far more the case that folks are muddling the issues. The common notion that "Mac must ship with phone to show commitment". There is no causal or physical parts relationship between the too.
There were no major new features in Mac OS X. Apple has highlighted 10.6 for the last 2 WWDC events. There is no significant 10.7 to show ( that's reasonable since relatively just shipped 10.6 just little over 6 months ago. Plus all of the iOS updates same division had to get out during that gap. )
Mac Pro should be coupled to WWDC . Mac Pro should be coupled to iPhone. Mac Pro should be coupled to iPad ..... what really motives those rationalizations?? Take a time out and think clearly about why that product should be tightly coupled to any of those. There is no good reason. Much more so, they serve as hand waving causality rationalizations for pulling dates out of thin air.
In contrast, Mac Pro coupled to new version/update of Mac OS X. Now that would actually make sense because ship Mac OS X with every Mac Pro system. They
are coupled. If they drop hidden support for new models in can release with some give on the exact date the update drops but they are related. (e.g,.
https://www.macrumors.com/2010/06/08/apple-seeds-mac-os-x-10-6-4-build-10f566-to-developers/)
Would not be surprised to see if new Mac Pro dropped and required 10.6.4 .
If folks critical to the Mac OS X release process were diverted to WWDC then maybe a delay due to that. I suspect they were not though.
iPhone availability a Mac Pro release probably isn't on Apple's immediate radar. Thus this Tuesday the 15th is out.
Folks made similar predictions that postponed new MBPro until after iPad shipments stabilized. Very similar threads proclaiming the sky falling because Core i-mobile procoessors had been released and shipping in limited models by other vendors ( not a fully line updates .... just partial updates) That really didn't work out. MBP shipped on the 13th. even while Apple was still dropping press releases about how magical the iPad was.
Apple is a big company (as much as they want to project otherwise). If they can't walk and chew gum at the same time they have major problems.
Between Janurary and now have gotten
iPad , iPhone
MBP , MacBook , ( some rumors Mac Mini drop soon )
The hype has certainly been different between the two major project lines. However, need to look at what Apple is doing as opposed to what hyperbole are spewing. Yeah Apple is much less likely now to heap major doses of hyperbole on the Mac line up. But is that really necessary?
