Just a note to say hi and great job
Well, at least Valve didn't KILL him. You never know that there may be an Aperture Science Space Station nearby...

haha probably not, didn't arial faith plates prove that participants cannot perform tests in space 
I think in terms of boolean variables. Generally, it makes things easier.
If valve makes portal 3... they had better be careful. Portal 2 nearly 'killed it'. Zero G testing would be...interesting, to say the least.
I was half expecting to see a combine space ship or something of the likes... valve really blew a HUGE way to tell a part of the Half Life/Portal story. Just seeing Earth from space could tell, (a dark side without city lights, etc.)
If Portal 3 was made, I'd picture it having a different main character. But I would bet it wouldn't be made until Half Life 3 was released.

As much as Valve seems to like thinking that they've finished off the Portal story, I doubt they'll be able to resist returning to it. Plus Steven Merchant already said he'd be willing to act again should they make another game, so prepare for ...
Wheatley's Space Adventures!
:O 
I think I've said this before but, to be brutally honest, I hope VALVe has the sense to not make a Portal 3. The story's ended! Let's face it, using the ASHPD in normal environments--cities, etc.--would be interesting but too hard to make puzzles for. And if they make a game that takes place back in Aperture Science they're just beating a dead horse. Yeah, it's great to keep playing new games, but there's a lot to be said for ending a series on a high note and letting it shine for the brilliance that it is.
I'd love to see Wheatley in more stuff though; general VALVe ads featuring him would be wonderful.
Now with 100% more inline comments!
If portal 2 is going to have a sequal, I have a feeling that Chell probably isn't going to be the main character, she escaped... gg. Technically Rattman is still inside the facility and GLaDOS has hundreds of new test subjects, that were stored, then found by the robots in the coop campaign.
I agree that having a Portal 3 would probably ruin Portal 2, however if most people who played Portal 2 will buy it then it might go into production.
Side note: Honestly having Wheatley trapped in space is a bit harsh, also you would think that Aperture had some kind of space station orbiting earth / he would eventually wind up at some space station.
Wheatley's Space Adventures!
I remember hearing Steven Merchant saying he would be willing to do more voice acting if there was a Portal 3. Who know, maybe Wheatley was responsible for the Borealis disappearing. That would be hilarious.

I'd rather see that prequel concept they were working on, along with the F-STOP mechanic.
If they're going to make more portal puzzles they should keep it to DLC.
