Apple's annual developer conference in San Francisco.
Mac OS X Leopard 10.5 at End of March?
This date corresponds to an earlier report from ThinkSecret that Leopard development was "wrapping up faster than many at Apple even anticipated". Based on this earlier report, the new versions of iLife '07 and iWork '07 are expected alongside Leopard.
Even after many false rumors about potential Apple media events, buzz continues about the possibility of a future Apple release event.
