[2] The Its-Coming-Soon Crowd.
Supported by the likes of 'iMacmatician' they believe the stacking of rumours throughout the year all point to a case design release sometime soon (August / Sept) with the Centrino2 (Montevina chipset) refinement. I confess to being the impatient type and finding myself wishing in this camp also. I don't believe Apple will do a big-bang, but that's just my opinion.
Pick a camp. Bet on black. Bet on red. It's all a collection of hope and opinion and all we can go is wait until the Apple gods reveal.
I'm definitely in camp 2.
I have been waiting on a redesign for a long time now and I can't wait until 2009. I really hope we see something in August with an upgraded GPU (preferably a GeForce 8800M). Also it would be great if they made a cooler running system that is more efficient.
