"The first big news is that MW3 will feature dedicated servers, which should improve connectivity issues. That will help with the bandwidth-demanding amount of maps due on launch day, as well as the planned DLCs. On the disc, there will be a whopping 16 maps. It sounds like there will be at least 12 add-on maps due over the year after launch, so by the end of MW3's run, players will have 28 maps to choose from."
And Bungie lied all these years saying dedicated servers wouldn't help glitching or hacking. Thank God Bungie's run is done!
