I'm personally disappointed with the fact that the digital upgrade is not available for people who purchased a retail copy. I admittedly did not do much research leading up to the release of Destiny. Since I purchased the retail copy (like I have with every newly released game I own) I would have to invest $100 for the game and the expansions after dropping $65 bucks already. I would be willing to pay a small fee even though I don't really want to so that I can keep playing a game I've grown to like. The way it stands though, I will not be purchasing the expansions or the Xbox One version of Destiny. I may revisit it from time to time on my old dusty 360...if I get tired of the Master Chief Collection.
