Come to think of it, who announces that there will be a big announcement pending? Is it an announcement or is it a rumour? Maybe announcing a big announcement is a big announcement by itself. There must be a lot of preparation behind the scenes before anyone can announce a big announcement. Also care must be taken that no-one will leak information about the announcement, or the announcement will be discarded as a rumour.
Bloody hell, there's a lot to think about here...
