While it's uncertain when more news regarding BioWare's next upcoming Mass Effect title will arrive, the game's most recent teaser trailer from November of last year has already begun to set a new tone for the series. It didn't show much beyond a mysterious, N7 logo-wearing character who could potentially be the successor to Commander Shepard. Nevertheless, the appearance of this unknown figure prompts speculation about when this next game is set to take place relative to the previous Mass Effect entries.
