I and many people in this forum are dreaming of, and expecting a lot more than that....
The Intel i5/i7 Processor
A Significantly Higher Resolution Screen (I would like to see the higher end 15" MBPs with both a Blu Ray Drive and 1920×1200 Resolution, Even if OSX has to be upgraded to render bigger text and icons at that resolution)
The ATI 5830 or 5850 GPU (Or any current gen (DirectX 11) mobile GPU with either GDDR5 Memory or a 256-bit Memory Bus. If this isn't feasible, an ATI 5830 at Minimum. All the Nvidia GPUs are two generations behind. The ATI 58XX series are the only half way decent laptop GPUs on the market.)
Blu Ray
Updated Display Port With Audio Output Support and/or HDMI port
The improved battery tech Apple recently developed (Already used in the 17 inch MBP?)
An improved HD resolution iSight Video Camera with Bigger Better Light Sensors
An Optional Matte Screen for those who want it, possibly an optional multitouch screen as well.
A HDTV Tuner & PVR Functionality so everywhere you take your Macbook, you would also have a HDTV that picks up HD signals off the air.
Oleophobic coating on the screen or maybe even the whole laptop
A Premium Carbon Fiber Unibody Case Option (Significantly Lighter, and if used as it is in sports equipment, damn near indestructable.)
Either 120GB SSD Drives or the recent 750GB 7200 RPM Laptop HDDs
USB 3.0 & If Possible with Light Peak
