Valve E3 event not happening?

From Geoff Keighley's twitter:  The  Portal 2 evening event at E3 is no longer happening. But the game will still be at E3! 
 
Pretty disappointing as I didn't think Valve would have an event just for Portal, they would have to show something else, like a HL2 ep3 trailer or maybe Counter Strike 2 or something new. 

Left 3 Dead 

They better announce the next Half Life game or I will end Gabe Newell

Well last year L4D2 was announced at the Microsoft Press Event, so it may have been moved into that or something. The game will still get a ton of publicity at this event even without this event, it's a shame they couldn't do an event though (probably fell into valve time and they postponed till next E3).

I only expected them to have Portal 2/ Thread title gave me a start, however.

I have to wonder if what they had planned  was cancelled and replaced by some viral marketing stuff because they're behind in typical Valve fashion, or if this is what they had planned all along.
