There was a lot shown at the reveal multiplayer trailer that screamed new and old. But this will not be the ONLY news of multiplayer. 343i are creating a second video tomorrow overviewing their choices for Infinite’s multiplayer. We can expect more news there. Though even then, that also wont be the last news as well. So stop siding so early and wait on it.
I look forward to future updates, the trailers were cool but a bit underwhelming for an E3 showing imo. I try not to put too much stock into these big media events though, in the end we will all know what the game is really like when it is released.
