Official UK PS3 magazine(about 2 or 3 issues ago, Google it) played a 24 marathon on PSN and they had some pretty bad things to say about it.
The real proof is simple play COD PS3 and 360 side by side and see how many times PS3 disconects etc whereas the 360 stays firm(and it is using voice chat). Both machines running on equal speed and same ISP.
