Bungie have given no information relating to if TTK will be in the digital upgrade program like the first two expansions. There is a high chance it won't be. Just keep reading weekly news and Twitter or just buy it for next gen as last gens will soon be faded out.

Hey - We actually don't know the answer to that question just yet. We'll need to wait and see if TTK will take part in the digital-upgrade program in the future. As of now only the two previous expansions may upgrade free of charge. Keep an eye out for updates and Bungie's [url=http://www.twitter.com/bungie]Twitter[/url] for more information in the future.
