If the MBP's went over their average lifecycle, the Mac Pros are meanwhile possible targets for an archeological excavation.
Eh, I wouldn't say so. the life cycle for MP is 11-13 months. The last update was March 3, 2009 (almost 14 months ago). If they get updated at WWDC, it would be 15 months. They'll probably get updated silently before WWDC (happened a lot in the past)
The last WWDC focused a lot on SL, in particular Grand Central. They don't have anything of interest to show yet (yay, 10.6.4!). They do on the other hand have the iPad and a new iPhone, both of which will be running iPhone OS 4 which has quite a lot of new stuff like multitasking. It's no surprise that they put all their eggs in the iPhone OS basket this year. You need a lot of imagination and conjecture to interpret that as the end of OS X.
You're taking this too far. Why would they end OSX if they just went through making SL -- the foundation of for future versions of OSX, with the new technologies and what not. Lets look at history.
WWDC 2005 focused on the Mac, particularly the intel switch, and Steve announced that the next version of OSX would be called leopard, and it would ship at the end of 2006 or early 2007.
MacWorld 2006 introduced the new intel iMac and MacBook Pros, and the new iLife suite.
WWDC 2006 unveiled 10 of Leopard's significant features, new Mac Pros, and Xserves
MacWorld 2007 had the AppleTV introduction, and the iPhone introduction. The event basically focused on the iPhone the entire time except for the few minutes with the ATV
WWDC 2007 (which keep in mind was a few weeks before the iPhone launch) almost completely focused on OSX Leopard, and the features they didn't mention at WWDC 2006. Steve also noted developers would be able to make webapps with the iPhone.
MacWorld 2008, MacBook Air, New ATV, Mac Pro updated a few weeks before.
WWDC 2008, iPhone 3G, Steve announced that the next version of OSX would be SL, and that it would focus on making the OS more efficient.
MacWorld 2009, new iLife apps, iwork apps, 17" MBP. No mention of SL whatsoever.
WWDC 2009, unveiling of SL, and a release date. New MBP's.
The technology and enhancement they made in SL are too great to drop OSX. They won't mention OSX at this WWDC, because OSX was just updated. Steve will probably at most give us the name and when to expect it, and in WWDC 11, we'll see 10.7. Remember, the iPad can't take over just yet. Just because they're focusing on the mobile arena at this point in time doesn't mean OSX is done for them. Why would they take OSX up to Open GL 3.0, why would they make Grand Central and all of these enhancements? Why would they update any of the Macs this year to the iX if they are going to abandon OSX and the technology it will utilize.
New Mac Pros, MacBooks, 27inch cinima display, problem free iMacs, and iPhones built correctly is what I'm hoping for. Oh... Xserve refresh too.
iMacs are problem free now. They fixed the bugs.
You forgot to add:
- iPod Touch with camera
- Apple TV (with apps for TV)
- Mini Tower/Mac Mini update
That's a list worthy of WWDC.
You won't see an iPod Touch update here. I'm 99% sure of that. Wait until September.
