Below is the original post, but Gameinformer has nnounced that it's April is going to cover details of Portal 2. Would be nice if more details came out, but this certainly helps my desire for HL2:E3 to come out.
Quote:Portal, as many of those with Steam may have found out, has updated twice int he last week.
the first update is described as:
'Changed radio transmission frequency to comply with federal and state spectrum management regulations',
The updates introduced a new achievement (Transmission Received) involving the placement of new radios in the levels.
The Second update is described as:
'Added valuable asset retrieval'
It looks like update 2 has changed the ending of the game, and now features robot sounds and a 'thankyou for assuming the escort submission position' after GLaDOS is defeated.
