So hear me out, I've got 5 facts supportive.
1) Sandy Bridge is released and available
2) New GPU tech (Nvidia 5xx and AMD 6xxx) is available
3) Update is overdue
4) 10.6.6. was released today (could provide hints for new HW support)
5) There is supposably an event on 1st Jan 11 for the Verizon iPhone
Apple wants to give a head start to competitors announcing their computers this week at CES and then steal the spotlight next tuesday with their new awesomeness filled MBPs (in the style of the new Air) and new great, lower-priced iMacs to gain marketshare. Apple's new concept of making big money through the digital distribution through iTunes, App Store feeds on big marketshare and they don't need to sustain such large margins from Macs selling outdated components.
