Read the verdict on Anandtech. The repackaged Penryn Macbooks/Macbook Pros's advantages over the older ones are a wash. Apple's probably being pushed to phase out the older processor by Intel in favor of the Penryns, because the window for Penryn-equipped Macs are probably going to be shortlived once Intel introduces Montevina in June. Now, THAT is a more interesting wait, and probably ,with Intel's push for smaller 45nm architecture in Montevina and Silverthorn(redubbed Atom now), THEN only we will see a case redesign for both the Macbooks and Macbook Pros. And THEN, only THEN will I be excited about the Macbooks and/or Macbook Pros, when the changes will be revolutionary, not evolutionary like the current speed bump and minor feature inclusions in the current lineup.

Correct. A tech lifestyle magazine reported that a possibility of software-updating the older Macbooks/Macbook Pros will enable Multitouch gestures, but later had to bring down that article after the teardown pictures shows that the Macbook Air uses the same Broadcomm controller found on iPhone and iPod Touch. The lack of this physical component alone ensures that older portables will not benefit from the Multitouch gestures.

Read articles on AppleInsider and 9to5Mac, that Sony did approach Apple for the BD drives, but 3 criterias of the offered BD drive did not meet Apple's expectation :- Not slot-loading therefore it is huge, high power consumption there for meeting Apple's battery life expectation, and Apple wants BR-R capabilities as well , not just BD-ROM.

It is of these reasons why we are still not seeing any BD options on the the current Macbook Pro. There are third party options for the Mac Pro, but not a BTO option from Apple themselves.

I foresee the next architechtural change to 45nm, power-saving envelope of the Montevina/Nehalem to allow BD to finally appear on Apple's portable Macs. Also remember that both the Montevina/Nehalem platform now includes Intel's own push for their GMA X4500 integrated graphic engine that will take the load off when it comes to processing HD files/discs.
