Naughty Dog, Developer of Uncharted 2, accidentally let the slip on Cross-Game chat coming in the next firmware update. On the PlayStation forums some one asked the seemingly innocent question of “why can we spectate our enemy when were dead?” in Uncharted 2. One of the developers gave a reply but accidently let a little information slip.
“…the next PS3 firmware update is going to allow cross game chat. So if players use that instead of in game communication then they would also be able to communicate enemies positions.”
Of course the post was quickly deleted , but with most leaks like this the damage has already been done.
