I would definetly buy this for wii u (or perhaps ps3). I could do with a seamless replay.

This free app is also coming:

Mass Effect: Datapad (2012): A free app for iOS devices. Datapad will allow players to check the status of the galaxy map in Mass Effect 3 and receive messages from characters. Datapad will also contain information about the characters, races, vehicles, weapons, and storyline of the Mass Effect universe, as well as mini-games that interact with the Mass Effect 3 'Galaxy at War' system.

Or then not. Too buzy playing Dragon's Dogma on ps3.
