Today’s big Apple rumor concerns Intel’s super-fast Light Peak connection, an optical (or copper) cable which can transmit just about anything along its skinny length. The rumor goes, quite convincingly, that the new range of MacBook Pros expected Thursday will incorporate Light Peak, and that Apple will rename it “Thunderbolt.” Then the rumors start to go awry.

The evidence consists of a supposedly leaked spec sheet for the new machine, along with a photograph of the actual Thunderbolt port and a screenshot of a promo page. Of these, the Thunderbolt logo looks pretty good, the port looks like it is a Mini DisplayPort with an icon Photoshoppped next to it, and the specs may or may not be legit.
