no not yet...
They don't make it(yet).
No, its only in your mind(and games, of course)
The price for Portal 2 has not yet been released, but you can expect it to be £49.99 - £39.99; the same as most games.
No you cannot make a snow portal without a mod and mods are yet to be enabled on 360 version so that would be a no.
In Portal 1 people say that Caroline hasn't had her mind put in but she kills everyone in the facility (Aperture Laboratories) so it is not that. So can you figure it out?
Nobody has managed to do this yet. If you figure out a way, you'll be a billionaire!
4J Studios hasn't put in The End yet but there's still portal frames (creative mode only)

Golden Temple Portal 5 Keep on taking a right, and you will see 3 statues, and then a portal. Do not go into the portal, yet. Go down, and then left, and now you will see a chest. In the chest is the Gold Key.
