Ok, it is really simple if you think about it. Madden knows that they f'ed up and now that 2k is back they are really going to have to step it up. However, Rome wasn't built in a day and neither was Madden. EA decided to focus on gameplay and incorporating their "last gen" features first and more than likely ran out of time to set up online leagues. If they had an intention to do it than it will be in next year's game but WE don't know why they won't do it. They could possibly be doing this to keep 2k in the game. Give Madden online leagues and who knows what will happen. Online leagues is 2k's cash cow imo. If Madden had that, then 2k would not sell that much.
I really want to see EA give 2k the license back and see if they can do a better job.
