There's a big chance that this will happen soon.
What I'm hoping for is a Macbook Studio sort of option.
Macbook Studio:
Thinner than a Pro
Uses onboard Flash Memory like Air
Includes internal standard HDD for media storage
Includes performance (i5/i7, 4-8GB DDR3 RAM, NVIDIA 330M) similar to Pro
No Optical Drive
More Batteries with less Optical Drive Space
the Macbook Studio (..sounds like a Dell Studio but nicer...but reminds me too much of Dell)
