Des,
Could you please tell us a date you will announce (any date will do...just make one up) but then don"t announce on that date.
Why?
because watching Pauline is like a watching a kid waiting for Santa and I"ve never had the balls to follow through on the threat that "Santa doesn"t come if your bad".
This would be harmless (I think!) and would provide a nice bit of entertainment whilst we wait for the actual announcement.
