Have not decided. I do not purchase "hype". Until the last Weekly Update, Bungie has been moot on the actual gameplay content details of TTK. Cosmetic items are irrelevant if the actual game is lacking content. Yes, Bungie finally started discussing the actual game portion of TTK. However, it is still not yet enough for me to drop $40 on a mere "expansion". Before the fanboys rant about "it's only $40, get over it", it has nothing to do with the cost per se. Luke Smith put it best, "it's about value". If I find that TTK has enough value for 3/4 the cost of a new complete game then I will purchase it happily. However, if TTK turns out to be more "smoke and mirrors" like the previous expansions then I will pass until it hits the "bargain bin". There are way too many first rate franchise titles dropping this fall. Too many to waste $40 on a mediocre DLC. If Bungie decided to drag out the game content reveal I will just wait until TTK drops to decide. It is not like there is any incentive to purchase it day one.
