OOOH Steve Parish - you big tease.
At around 2.30pm on Friday afternoon, the Crystal Palace co-chairman tweeted: "Stand by for an announcement."
But two and a half hours later at 5pm, no such announcement has been forthcoming, leading to some amusing suggestions and conversations between Eagles fans on Twitter - speculating seriously and not so seriously about what the news might be.

@ohsouthlondon Tweeted: "Marco Gabbiadini was actually Marcia Gabbiadini and was the inspiration for hollywood blockbuster 'She's the Man' #cpfcannouncement #cpfc"
The only news from the Palace official Twitter feed since Parish's teaser has been the relase of a YouTube video about the Eagles squad visiting the steps in Philadelphia made famous by the Rocky films.
The most likely content of the announcement is that Palace have completed the signing of Cardiff striker Frazier Campbell, heavily linked with a move to Selhurst Park in recent days.
But some are hoping for more dramatic transfer news, with @samjordan Tweeting: "Ronaldinho isn't playing in Deco's testimonial match tonight. Read into that what you will."
