Quote, from Valve's e-mail to press:
"Dear Subject Name Here,
Aperture Science is pleased to inform you that we have partnered with Valve to announce the gala CANCELLATION of the June 14 Portal 2 event at the Regal Theater. The event will be replaced by a surprise. And even though the cancellation of the event certainly counts as a surprise, we are pleased to further announce that the cancellation of the event is not THE surprise. However, per International treaties regarding the definition of the word "surprise", of which both Aperture Science and Valve are signatories, the time, date and content of the actual surprise will only become available as you experience the surprise.
If you'd like to ask fruitless questions about the E3 Portal 2 surprise or, more fruitfully, schedule an appointment to attend a Portal 2 screening at the Valve booth during E3, please contact Valve's Special Envoy to Surprises, Doug Lombardi.
Thank you for **RECORD SCRATCH!!!**
PS: The surprising record scratch is also not the surprise."

lol
Well, that letter is a surprise. Love the humour.

Haha, neat. It's nice to see game dev's/publishers still having a sense of humor in the age of sterile gaming experience. Anyone [yeah, Vagabond;P] remember the Crusader manual for example?
So it's gonna be Episode 3 with the portal gun, and Portal's overall length, since, the Valve Theory i have states, that the longer it takes for them to write a game, the shorter it is.
Or perhaps it's a stripper jumping out of a cake.:)
Or, no cake at all, since it was a lie, or something. Or they'll play that annoying Portal song over and over again, causing everyone's head to a'splode.;>

Well it's about time for L4D3, isn't it?
Only thing is: that wouldn't be a surprise. Given how most people think that Ep3 has dropped off the face of the Earth, that could be the surprise. But the only thing surprising about that would be that they have indeed been working on it.

I would die of excitement if it happened to be Episode 3.
I will die of disappointment when it isn't Episode 3.
It looks like I'm screwed either way.

"Humour" nowadays is often misspelled as "ARG". I don't know if this is the case or not. :p
Maybe it's time for L4D3, yeah...
And I'd be surprised for sure, if we end knowing that Valve actually worked on Ep 3. A hell of a surprise, you've been doing something else other than TF2 updates and the L4Ds for these 3-4 years!!1
Indeed, both.

I give it a week before there are a dozen RickRolls on YouTube claiming to be *NEW* HL3 footage.

It's their Puzzle Based MMO (puzzle meaning tile-swap game).

Hah yeah I agree.

what about Opposing force 2: Episode 1

Don't start with that!

Oh GLADos, you twisty twisty bitch....

This was a triumph!
HUGE SUCCESS!

The surprise is a lie!
