Although this shouldn’t be taken as confirmation an HD remake is in the works
Putting the question out on NeoGAF, Flynn started out with a list of items that have already been requested by fans. 1080p, 60fps, shader enhancements. high resolution textures, all DLC included and a seamless experience where the three games would flow into each other without having to go back through menus were all mentioned.
A number of suggestions have come back including controller support for PC and updated combat mechanics for Mass Effect 1. One user brought up the organic implementation of the DLC for each of the games in the series, so that it unlocks as you reach corresponding points in the story, to which Flynn responded, ”‘organic implementation’ is definitely what I have in mind, [The DLC] should just all be there, as if it never wasn’t there (if that makes sense).”
While the tweaks required to make an HD remake of the Mass Effect Trilogy shine are clearly on the minds of some at least at Bioware, Flynn did state in his post that this is just a ‘wish list’ for the time being. He later mentioned on Twitter that a Mass Effect Trilogy remake won’t be announced during the N7 Day live developer roundtable.
Looking forward to #N7Day14! Unfortunately we have no news about the Mass Effect Trilogy coming to new consoles. When we do we'll share ASAP— Aaryn Flynn (@AarynFlynn) November 6, 2014
