I think a statement such as " It really is a trivial feature that adds nothing." just makes it look like you're trying to downplay a feature millions use everyday and do find useful (thats a fact and not opinion).  I agree it's importance is overplayed by some but then again it's the same when people discuss a console having 2 or 3 more exclusives a year when there is 10+ multiplatform games released of equal quality for the consoles in that year.  You cannot have it both ways.

I gather you were never a particular good CSS player if you couldn't concentrate and use Vent or Teamspeak while playing.  The only time I'd ever get annoyed is if you had someone in the channel bleeding the mic with background noise when they spoke, this was infrequent though as I played with gamers I enjoyed talking to which is the exact same thinking behind console platform chat.  You play with people that aren't going to irritate you with crap all night, thats no different than any other social interaction. 

In summary, I'm of the opinion that you've really not got a clue what you're talking about or enjoy playing with ass hats who cannot behave im a chat channel to have a opinion that it's not useful at all...

This is true, I think they tried to add it in when they added in-game XMB but the PS3 hardware simply does not have enough RAM for both the game and voice chat to function simutaneously.

Answer: The PS3 will never get cross game chat, but the PS4 and Vita will have it at launch.

I think it will really soon. Since they've added the feature to Vita and they've been saying that they're "Working on it", "Looking into it" and that "They know that the community wants it". I wouldn't be surprised if they launched it alongside the PlayStation Vita or before it.

If not in an upcoming psn update then probably ps4, but hopefully it'll come on an update soon...

Maybe when psv is released it may come in an update
