Well, the new patch fixed some issues but many still remains the same. The D-pad lean works pretty good but I never really had an issue using the sixaxis. The grenades are now stackable which makes it so much easier than throwing 2 then selecting the other half of grenades.
The Score Board is also now slightly transparent. We have more time at the end of a match to mess around, pointless IMO. Hmm... what else, oh the lobby screen can now be set alphabetically which helps finding rooms easier and the room that your in also shows underneath your PSN - ID.
Thats about all that I can think of at the moment, there is still lag on occasion but not too bad most of the time. If anyone else wants to elaborate on their patch experiences, by all means please.
