Mass Effect 4 released.
Like I've said, the time passed between the release of Mass Effect 3 and (if we run with the rumour) a VGA '13 announcement of Mass Effect 4 would rate as the second longest down time between two mainline titles either announced or released. And a March '15 release would be
the longest gap in the series by a long shot.
Entering a new generation with new hardware and a (relatively) new team heading the project would add some time to the schedule, but if the above is accurate it's all accounted for, in my opinion.
I hope its not CGI trailer, like two VGA's ago.
I want in-engine footage with some short gameplay scenes Bioware!
I don't think we'll see actual gameplay. If the VGA rumour is true I'd expect it to follow the same pattern as Mass Effect 3: press coverage early next year in magazines from private demos, first formal gameplay footage at E3 2014. VGA reserved for the teaser video hinting at the themes/narrative. And given this is running on Frostbite 3, I wouldn't be surprised to see it all in-engine, like Dragon Age: Inquisition's reveal.
