You know, I think that this whole "big bundle" business model is kinda detrimental here. I feel like they would be able to make a lot more money and prolonged the game's lifespan a bit if they'd had a team just to work on making all the little excess stuff (armor+weapon skins, stances, armor) and released stuff more frequently to a world with micro-transactions, allowing people to just buy the one or two skins or whatever they wanted. They should still keep releasing the map packs as usual, but hey, why not also open the map packs to purchase individually after a few months.
I don't know, it just seems like crappy buisness...ing... On microsoft and 343's part to just lump a bunch of random extra crap in with the last map pack.
