"The extended ending is basically going to be part of the game instead," series producer Michael Gamble told Siliconera during Comic-Con. "You won't have to download it." That makes sense given the DLC's status as a "fix" for the controversial ending. We can only hope the ending is extended even further, to show you even more ending on the WiiPad screen while the Extended Cut ending is happening on your TV.
The Wii U release of Mass Effect 3 is scheduled to coincide with the launch of the system.
