Eldar said yesterday that N9 would not be introduced in Nokia World so i guess the info is from there. He also said that the device would get delayed release till q1.
I'm starting to believe too that N9 will not be introduced in NW, not sure about the release date as Eldar said the same about 5800 and N900 that both did come out Q4 but did come out in Q1 in Russia thought.
