I doubt it......
1. the MacBook is polycarbonate, while the MBP is aluminum
2. Apparently Apple spent lots of time researching the "perfect" color for their machines for the best viewing experience. For iMac, MacBook Pro, Cinema Displays....then they make their computers the same color, Mac Pro, Mac Mini....etc
Since now the only two colors of machines are silver and white, I doubt black will be put back into motion....especially for the MBP
Saying all that, I am still a little stumped why they put a black boarder around the 24 ACD, iMac and MBP.....when I remember Apple was very proud of the color silver they chose....hmmmmmm
