What about NAB
 

Interesting Apple would release a processor upgrade just before NAB. Obviously, there will be software to match.

I agree. NAB is going to focus really on the PRO APPS. I hope Jobs does a Keynote...if he does, he is likely to mention how the Apple TV is going, and hopefully will say "we are adding HD movies with Surround Sound to the iTunes Store."

As I said in another thread, don’t be surprised if Apple unveils a new MacBook Pro at the NAB as well.

Quad-Core maybe?

I am going to be buying a new computer by the end of summer (I still only have Powerbook G4 1.33, 2 GHZ RAM). I bought this when the Dual G5's were out, but needed a Laptop. The same principle goes now. I really think I would be fine with a MAXED OUT iMac (3 gigs RAM, 750 Gig Hard Drive, 24 Inch Screen, etc), but I do not want a Dual Core Chip since it is so far below what Apple is starting to release now. I want the next CPU I buy to last a little longer, and I don't need a laptop this time around.

I am hoping that Apple adds a Quad-Core to both the Macbook Pro and the iMac 24".

Apple have always been known to charge a whole lot of money for upgrades such as RAM, etc, but with this latest release, the prices isn’t that bad.

Apple even lowered the prices of the monitors at the same time and something tells me that the reason Apple is releasing this computer before NAB is to get rid of those monitors so maybe newer versions will be shown at NAB.
My guess would be at least a 24” 1920X1200 display with HDMI 1.3 complaint ports.

Quad Core mobile parts won't come until the 45nm Penryn processors are delivered in Q3 of this year. I think that the iMac will be going quad core as well this year.
