Anyone else think that Valve might spring a surprise on us and bundle HL2: E3 with Portal 2 in something similar to The Orange Box?

Everybody's expecting a bundle. I think the surprise will be that Portal 2 and HL3 will be the same game, or rather interweave seamlessly. You won't even know you started playing the other game until a title card pops up out of nowhere... or the title card for one will be the intro and the title card for the other will be the outro.

I just hope that they just admit it to people and say Fuck it, Half Life 3 is coming out next year or more likely 2012
 
They gotta admit that they really didn't understand the concept of episodes considering how much time they are taking

No, but I'm sure Portal 2 will bridge the gap between the two games in a much bigger way.

I think Portal 2 will be just that: a sequel to Portal 1, and that there will be no box whatsoever.

I would be cool. Also awesome if it came with team fortress 3 or counter strike 2

That would be great.  Personally I was thinking Portal 2 and Episode 3 would be the same game.
But I don't think they are going to do this, I think they are going to give each their own proper release.

Episode 3 will be scheduled to release on December 22nd, 2012.  It will be the greatest creation man hath ever wrought.  Unfortunately, no one will ever get to play it.
