Steam and Lag for Orange Box on PS3?

May be...

I've been thinking about getting The Orange Box for PS3, only for Team Fortress 2. Is it worth it, and will I still get updates from Steam, even though it's not for PC? And are there any outstanding lag problems?

I would get it. That's why I bought it in the first place. I love to play TF2 it's really fun and doesn't lag. I'm not sure about the updates though.
