Here's the deal. Had MS said they were going to pack in something like Ryse or Forza, then yes, it would be a generous, great move and would change some things.
They chose to pack in FIFA, a game that (a) will have been released almost two months after the XB1 releases, and (b) potentially already released on the PS4 for several weeks. It is a game with a fast shelf life, as are many sports games. The PS4 is still a cheaper option even if you buy FIFA and PS+ along side it. And it follows MS decision to delay the XB1 in many Euro countries, putting the FIFA pack in back till 2014, which is absurd.
We don't have all the facts of course, so maybe this will be a better value proposition if MS got EA to delay FIFA PS4 until the XB1 is released. But as a pack in game, this is business wise a fairly stupid move. MS thinks that gamers will wait patiently until the XB1 is out to get their FIFA fix. I say that's silly, but we'll see once we have more info tomorrow. It's not hard to see why people would think this isn't a touchdown hail mary pass to win the Super Bowl.
