That's the thread with this at the start:-

Balance and Updates currently in Development and/or Discussion:

Timer countdown tick fix for PS3. Both in-game and in-lobby.

Further improvements to network performance.

Further improvements to the spawn system.

MP music volume remix.

They've mentioned several times in several posts that a network code update(lag comp) is being worked on and shall be implemented, when?well 'how long is a piece of string?' The recent issues with dlc updates, 18 man lobbies, black loading screens and hacker intensity might be slowing them down a bit to focus on the main issues for most of us that would prefer to just play this game and not ***** about it.

As for the spawns all I've figured out is that they're aware of the issue and some say it's not even fixable. They're collecting data for bad spawns ie dead within 3 seconds but i'm not sure of this counts for being killed by the guy you just killed too.

FFA might be the worst I've experienced but I've had bad spawns in all game modes I've played and the map layouts could be the biggest issue with fixing the spawns for them as with giving us quick cqc maps the safe zones for spawning are few and far between but this doesn't count for all maps.
