Except that Apple and Disney are so close - and Disney is all BluRay. Since they get about $10 more per disk for BluRay than for DVD, I'm sure Disney would like BluRay to catch on.
I don't have any idea when it will happen, though.
Mac OS Rumors had a report that the MBA was going to be updated with Penryn at some point,
I posted a sarcastic reply ("Well, gee. When Intel releases faster chips which consume less power, Apple will put them into their laptops. I'd never have figured that out on my own. Thank you so much, Mac OS Rumors."). They never posted it.
It may not make a computer that fits YOUR needs, but it's hard to see that the iMac is 'multiple steps below a Mac Pro' for most users. You can expand RAM high enough for the vast majority of users. You can add as many external hard disks as you need. The processor is plenty fast for the majority of users.
I'm willing to bet that for 90% of non-game players and non-graphics professionals, there is no real difference in usability between the iMac and the Pro. If you're a professional or an avid game player, you need the pro.
Of course, there are plenty of people who want the Pro, but want it at half the price, but that's too bad.
I just don't see a significant number of people being left out between the iMac and the Pro.
If we ever get to the point that Apple is in business only to satisfy your needs, that might become relevant.
Yes, for top-end gaming.
The MBP isn't meant to win any Quake frame rate contests, however. If you want killer frame rates, you get a desktop with multiple graphics cards. Laptops aren't (generally) meant to be the top end gaming machines.
