Heads-up, BDP-S300 owners -- Sony has just unleashed a new firmware update for your machine. Posted today, the v3.90 update will bring you, well, we're not exactly sure what. According to users at AVSForum, the general consensus is that TrueHD support just has to be in there, but Sony's servers are so glacially slow that no one has been able to confirm or deny just yet. Once your download manages to complete (hey, it takes awhile when it's being uploaded from what appears to be a 14.4k modem connection), feel free to discuss any notable changes in comments below.
