I do agree that alot of people have that deep, intense emotional connection with the game, its characters and the entire series as a whole and thats what keeps it alive. I know for some that the endings were considered a total disappointment, but for some they were happy with what they chose. For me at least, no matter how many times the games are played that deep emotional connection remains there regardless, the crew you know and love, help out when needed and have fun with, always to be remembered.
I dont think for a moment that the devs will abandon that, its clear as day this connection we have to these games and im sure that will be reflected in the next title.
I continue to have faith that BioWare are going to deliver something absolutely amazing with the next ME title while still letting us have a slice of the previous titles in some way too.
