Some readers have noted that Apple has pulled the Logic 7.2 crossgrade from its Online store. This has lead to speculation that the rumored Logic 8 (perhaps revamped (page 2)) may indeed be released this week at MusikMesse in Frankfurt, Germany.
Logic 7.2, a universal version of Logic, was released in February 2006. The last major release of Logic was back in September 2004 when Logic 7 Pro and Express were introduced.
Update: User 4God notes that Final Cut cross-grades have also been pulled. Final Cut Pro is expected to be updated at this year's NAB conference.
