wbr1 (2538558) writes "The Escapist has an article detailing the fact the the recent trademark filing for Half-Life 3 has disappeared from the (legit) site it was on. It also states that it would not be hard to hoax a filing for a company that already has filings, but it does cost about $1200 to file, so not a cheap hoax. In adition, it appears a filing for Portal 3 has now appeared.
Personally I think Valve is a master of this type of social manipulation to keep interest alive."
