Well it was done for Pulse, it seemed to be able handle the situations you describe when someone quits and dies then quits. I'm confused, is the PS3 that much harder to code for that death is death was so hard to do?
I'm not retracting anything till I've played it and been convinced otherwise, how does it not remove a load of strategy and thrill? Your not going to get that heart thumping sensation when the HUD starts screaming at you telling you your about to die and you have someone behind you that could potentially finish you off at any second because you know, oh well I'll be brought back to life, who cares...
If that video is accurate it looks like 4 seconds from death to respawn, hardly enough punishment.
Hope these possible updates become a reality for the not too distant future.
