Blu ray licensing fees are still 4 times the price of DVDs. Microsoft isn't stupid. Bandwidth cost vs a second DL bluy ray disc. Unless they changed their plans, they are already having dedicated xbone servers for each halo games' multiplayer playlist of this collection. That's even more money they are spending. It's likely they figured out a hit in bandwidth fees was better then having to pay the blu ray foundation more money. Don't forget Sony's a key part of said foundation. Why would you want to give your competitor extra money when you don't have to? Plus it has already been shown when ever a halo comes out, xbox sales and gold subs get a big spike for 1-3 months. The gold subs and xbone sales may make up just enough of the bandwidth cost.
