OK, so we know that Panasonic and Apple may have something together (or not), but it could be something on the lines of a new panasonic camera with firewire 800, and some other nifty new features that work with FCP4.
I was thinking it could also be something with consumer oriented devices, but not at NAB.
As for the IBM thing, they may introduce some sort of partnership with Apple to sell them the 970's, but 1.) why would they do this, isn't there the AIM alliance? and 2.) this is NAB, and a upcoming processor thing really wouldn't do much.
unless...
Unless Apple has plans for a super high-end digital video workstation in the works. Something between an xServe and the current PowerMacs, with a 970 (or duals), the hard drive scheme of the xServe (4 independent ATA-100 channels [or even 133 or higher]), 2 or more video cards (1 plain jane nVidia or ATI card, and another special high end video capture card or something like that), and all the bells and whistles.
We know that the next PowerMac release will have 970's. The only thing is that NAB doesn't seem the right time to unveil them, or say much about them. Unless IBM is going to say something about it without word from Apple, you probably won't hear anything 970 wise from Apple.
Just my $0.01 (due to inflation, my $0.02 isn't worth as much

)
