No, I think it must be something bigger. For example, the iConsole. Apple is going to compete with the XBox and the PS3.
What I also like to see are non-glaring screen finishes as an option for the iMac models.
There will not be 3 models. A Mac Pro with PCI slots is just a temporary stop-gap like iPod Classic until all the PCI card vendors have transformed their products into external Thunderbolt devices.
The future will have a small Mac Mini and a big Mac Mini, the latter with the required cpu/ram for server purposes.
The current Thunderbolt implementation transfers up to 10 gigabits/second bi-directional. [1]
The current PCI-E X16 slots in the Mac Pro transfer up to 64 gigabits/second bi-directional. The future PCI-E X16 standard (3.0) has 128 gigabits/second bi-directional. [2]
Over the next decade, Thunderbolt transfer rates will reach 100 gigabits/second bi-directional. [3]
Thunderbolt is nowhere close to replacing PCI-E slots within computers.

Why would Apple release an iConsole and not just add those features to the AppleTV?
Therefore, Apple will probably have designed the iConsole in a somewhat more exciting look than the usual Apple products, which are all quite minimaistic (which I like, BTW).
