Bioware has teased many times already on the possibility for Mass Effect Trilogy Remastered to get produced. With Mass Effect 4 coming out on the Xbox One and PS4, it seems that a remake is truly needed for the new-generation consoles.
However, there are some things that Bioware need to offer in Mass Effect Trilogy Remastered in order for the game to sell well. For starters, Mass Effect Trilogy Remastered must come with all the DLCs included. We would hate having to pay for the same DLCs all over again.
Then, there is the need for the remake to come with improved graphics. After all, each Mass Effect title was built on different game engines and things need to be standardized in the remake.
If Bioware is able to deliver Mass Effect Trilogy Remastered with the above in mind, there is no doubt that the remake will sell well. After all, there is no better way to start on Mass Effect 4 than through playing Mass Effect Trilogy Remastered.
