Unfortunately, I think the Ace Attorney series is pretty much dead at this point; Spirit of Justice apparently only barely broken even, and Dai Gyakuten Saiban 2 was a colossal bomb. There'll very likely be an HD re-release of Apollo Justice at some point, as they already remade all the artwork for the iOS/Android release, and maybe an HD remaster of Dual Destinies and Spirit of Justice, but unless the most recent re-release of the series sold well enough on PS4 and Xbox One to justify a fully multi-platform entry, I don't think Capcom are going to commit the time or resources necessary for an HD Ace Attorney game.
