Being an crazy Portal fan (bought orange box for portal and loved it) i am so hyped for portal 2 more than any other game even LBP2.
But what got me thinking was that Portal 2 was unveiled during SONY's press conference and for every 3rd party game shown off at Sony's press conference has some type of exclusive thing attached such as MOH front-line in MOH PS3 version, ACB beta test etc etc
So what about Portal 2, can we expect some exclusive content heading PS3 way??
I suggest that Portal 1 will be on the disk of Portal 2 since Blu Ray size. but there something like steamworks?? heading to ps3 for portal something like that, is that the exclusive thing happening.
Of Course That's Just My Opinion, I Could Be Wrong
