Recently, Treyarch game design director David Vonderhaar responded to concerns on Twitter, saying, “we’re testing back-end changes to help allow alleviate some of the matchmaking issues. No time table yet.” He later added, “we are indeed up and running, but we are also aware not everyone can connect. We are investigating something with our partners at Sony.” Fortunately, it looks like some progress is being made. Vonderhaar’s latest statement read, “we are currently testing backend matchmaking changes that we think can help with this. I don’t have a time table, or I would tell you.”

Those still experiencing system freezes, another known issue with the PlayStation 3 version of Black Ops 2, will have to wait for an upcoming patch to alleviate the problem. A few hours ago, Vonderhaar tweeted, “we found and fixed one known PS ‘freeze’ so far. Unfortunately, it can’t be hotfixed and hast to be patched.”
