Basically, he's saying that the February event would be something rare and unusual for the Apple we have known. I suspect this is likely a hint having to do with this being the first major product introduction since the death of Steve Jobs.
By the way, how about that Gizmodo.jp rumor? Check it out. Looks pretty fake to me, though it seems to have blown up all over Japan today.
Actually some would argue that the iBooks 2/iBook Author launch was the first major product introduction since the death of Steve Jobs.
While the iPhone 5 on the Gizmodo site is obviously a fake, it is very nice!
