But Intel is not supporting it so I think Apple's hands are tied until they do. It does seem like a strange thing not to support until of course you factor in Intel pushing their own alternative (Light Peak?).
Intel supports many things long before there's a point to them (eg DDR3 when it had no tangible benefit over DDR2 (initially) and cost 4x as much).
I used to think that Blu-ray would come to Apple when it was sufficiently cheap. I've changed my mind on that. I think there's a fair chance it never will. I can see optical drives disappearing altogether. If you want one, it'll be a USB peripheral.
Some Macbook owners replace the optical drive with an SSD (or their normal HD with an SSD and the optical drive with a spindle HD for storage). I would actually really like to see a Macbook that came as standard with two hard drives.
As it is, Intel is updating their (excellent) X25 HDs at the end of the year (or early 2011). My next MBP will probably get one of those (150 or 300GB).
