This isn't going to hurt Valve as bad as a lot of you seem to think it will. Most of the people that will abuse this are people that have a gaming PC. If PS3 ver didn't come with a free PC copy, those people would buy the PC ver. Valve is still getting $$ from the PS3 sale. Do you really think there is going to be hundreds of thousands of people waiting to buy PS3 Portal 2 used?
Edit: It also seems that some of you think Steam=Steamworks. You won't have access to the Steam store or games on your PS3. But you will get updates through Steamworks at the same time as PC...
