A PS3 specific Modern Warfare 3 hot fix will be released imminently, ahead of title update seven later this week.
Following a hot fix earlier this week, Infinity Ward creative strategist Robert Bowling said on Twitter today:
"Pushing out another #MW3 hot fix, hopefully tonight, possibly tomorrow. Fixes hitmarker sounds on PS3 also Semtex+Juggernaut rebalance."
"Adjust direct impact damage a Semtex does to a Juggernaut (No longer 1 hit kill)," the Call of Duty site elaborates.
"TU7 will be sometime this week," Bowling added. "Depends on cert process, we're done and submitted."
Bowling also confirmed a MP1st report that an Xbox 360 player has been "temporarily banned" from playing on the MW3 servers for 5,000 days.
"Player Banned for 5000 days?!" he said. "Yes. If you see this message, it means you've been Permabanned (for something bad)."
