What we can expect, though, is a huge amount of panic buying. And industrial-strength stalling from the berks at Sky Sports News, who've been preparing for this hallowed day for the last seven months.
Andy Burton will be being interviewed in the studio every 45 minutes or so, saying his sources are saying their sources are saying that someone is getting on a plane to somewhere, but he can't give us any details because he needs to keep it private. Meanwhile, Jim White will almost certainly be trying to convince us that Sunderland signing Peter Crouch will happen, and that it is every bit as important as the giant shock transfer we're all waiting for. Adam Leventhal will try, and fail, to get a nice view down Natalie Sawyer's cleavage.
The BBC live text system will be as dull as ever. Sam Lyon will retweet some tool's lies about Sergio Biscuits being seen travelling along the M60, possibly tongue-in-cheek but you can't be too sure with Sam, he might just be a thicko. Jonathan Stevenson's updates will be pretty reliable, but just five minutes after you've read about them in the next day's papers. God, he's slow.
Owen Hargreaves is looking like being the comedy story of the day, probably being subjected to cotton wo- erm, "fitness tests" at various places, allegedly Manchester City, which is funny in itself. I'd bet cash money on him failing, regardless of what YouTube tells you.
But forget everything else. Tomorrow is about Arsenal. They'll be referred to as a crisis club dozens of times, the words "pivotal", "crucial", "vital" and anything else you can find in the thesaurus will be banded around in reference to the day's importance to Arsene Wenger's time as Arsenal manager, probably by Craig David, who's my tip to be stationed outside the Emirates with that big façade of the Arsenal legends linking arms in the background. You know the one.

And in the end, it'll all be a massive disappointment. Stoke will sign an average Championship player, Arsenal will panic buy someone unproven but with promise (cue ominous music), and Leventhal won't see any boobs. I can't remember a truly interesting transfer window since that aforementioned wonderful day in 2008. At least this one won't feature the saga of whether Barca will make a late bid for Cesc Fabregas.
We all know it'll be rubbish. I've told you what's going to happen already. But you'll still skive off work and be glued to the tv, your phone and/or the internet all day, won't you? Of course you will. And I'll be right there with you
