Several musings seems to have hinted at 17" MacBook Pro, and the MacPro desktop getting attention at MacWorld, after the first of the year.
It would make sense, to generate some Laptop buzz AFTER christmas, while MB and 15 MBP are generating it now, and perhaps iMac and Mac mini joining in.
I would think that MacPro would wait for i7 chipset revisions. Why not wait until 1st quarter for that? MacPro is hardly hurting now.
iMac and Mac Mini... I hope they get updated in November, and the sooner, the better.
iMac probably will get an invisible update. It will probably be physically indistinguishable from the current model, save for perhaps a vent, or a port difference. Maybe a higher resolution screen, or something...
Most of the changes will probably be upping it to equivalent equipment to the new laptops, Nvidia chipsets, and such.
I hope the Mac Mini gets a more thorough overhaul, and perhaps a bit of refreshed emphasis. Hopefully it is very configurable, from quality headless bargain value, to macbook Pro like stats, that can be configured to be more of a serious compact stationary machine, even if it is based on mobile parts. It should stretch upmarket a bit, should one want to pay for it, and hopefully dual-display capable, and hopefully capable of running 8GB of DDR3 someday in the future, if only 4-6GB now, like the MBP. Good hybridSLI graphics, or some sort of video system upgrade would be nice.
And I REALLY hope none of them lose Firewire. That would just be insulting to customers who use firewire equipment. MB losing it was bad enough.
