Honest question, why not just ship 2 disks? Especialy since it all installs on the harddrive anyway, and just allow the user to have either disk in the drive to play?
20GB download rather hefty. It would take me a couple of hours to get it down if I decide to buy the game. I am almost exclusively physical media for consoles, so this is a bit of a hassle. It's a bit disappointing, only because it seem like an issue that could be avoided. I was wanting to hop into MP right away.
Unknown, but then that's the problem with everyone jumping to all these "inept" and "anti-consumer" conclusions. There's more than a few reasons it could be. I
highly doubt an actual patch could be installed from a disc on Xbox One, and it's possible that installing add-on content from a disc isn't (yet?) supported by the console either (the fact that it works on 360 is largely meaningless here). Also, even if add-on content from a disc is supported on Xbox One, there are still reasons why it may not be feasible. We don't know what exactly is contained in the update, but it's entirely possible that programming the game to take in whatever content is there as "DLC" would be technically infeasible or would at least take much too long, especially if the need for more space wasn't established until too late in the development process.
Basically, we don't know enough yet to make all these hasty judgments, particularly when "to save money" doesn't make much sense (the cost to print a second disc is basically negligible, and it's not like millions of people downloading 20GB of patch data at once is exactly
ideal, even for MS) and the whole "they're just stupid/inept" thing is just, well, stupid.
