Doubt it's a glitch. Like most problems in this game, it's pure lag. I don't get how Killzone 3 has dedicated servers and has sold millions less units than Uncharted 3. ND should be able to fund dedicated servers for at least 3 years. P2P after a few years will make it unplayable laggy due to a smaller more dispersed pool. So much wasted potential due to net code with this game.
