The MacRumors Buying Guide has it a bit past mid-cycle, and if you look at the average update span (189 days), you'll see it's on track - if history is anything to go by - for
possibly something happening in another ~60 days (mid-March or early April...probably about the time Leopard is ready to roar, and when the shipping delay in the iPhone will be announced).
Then again, murbot's recent purchase probably seals the deal at an announcement next Tuesday.
