Valve has sent word that Portal 2 will be coming Holiday 2010.  However, there are some underlined letters located on the Steam News Website:

Valve, creators of best-selling game franchises (such as Left 4 Dead, Counter-Strike and Half-Life) and leading technologies (such as Steam and Source), today announced Portal 2 for shipment this coming holiday season.

Portal 2 is the sequel to 2007’s Portal, which won 70 industry achievement awards.

The underlined letters spell "drattmann" and "h0nee" (which is really "honey" as the password) are the username and login for the BBS number that valve has setup at (425) 822-5241

If you happen to live in the 425 area code, give it a ring on your modem with Hyperterminal or another dialer 🙂
