What about the Extended Cut for ME3? For many people, it did provide a lot of answers, a lot of clarification and closure. I am looking forward to seeing new DLC will become available for ME3.

With the whole idea of ME4, I am wondering what kind of new character we could possibly see, I am hoping for a whole new trilogy.

According to the website, this Logan Marshall-Green could be a good fit for the starring role of Commander Shepard:

Mass Effect 3 was in no way a "let-down", it still remains to be one of the best titles for 2012, even with the endings of ME3. I respect your opinion, I still do not regret the buying the N7 Collector's Edition and spending a lot of my free time playing the game, multiple times. The original endings to ME3 made no sense, but thats what the point of the Extended Cut was made for, was to provide answers to the questions many of us had and give us some kind of closure. I will still say there are a few questions left unanswered, even after the Extended Cut, but I am still satisfied with ME3.

I can't wait see what the future may hold for this great franchise, with the hopeful release of Mass Effect 4.
