IGN have whiffed up their new 2-page interview with Kim Swift of VALVe Software regarding Portal, of course. Here's a slice:

"IGN: The demonstration at EA's Studio Highlight was excellent. Some things that we wanted to clear up, however, stem from Portal's separation or integration into HL2: Episode 2. Is it a standalone game or it is part of Episode 2? Also, we gather from the demo Portal is a single-player game, is this correct? If so, will Valve develop it into a multiplayer game in the future?

Kim Swift: Portal is a first-person, single-player game set in the Half Life universe. It is a stand-alone game that will provide an extra three hours of gameplay to the HL2: Episode 2 game package. The initial release is to be single-player only, but we have lots of ideas for multiplayer with Portal for future projects."
