Marvel Heroes has something of a tradition of rebranding now, with each new year bringing a new edition of updates and improvements to the game. An extensive set of updates are planned for Marvel Heroes 2016, and it’s all just about done… except it could apparently use a little more time being polished up. Thus, it’s being delayed until January of 2016 instead of its original planned release in December 2015.
The launch of Marvel Heroes 2016 has moved to Jan. 2016. Everything new is in great shape – we just want to make sure it’s perfect for you.

Subsequent replies indicate that despite the delay, the Danger Room will still be available this month. No specifics are yet available for the game’s next mega pack, which may or may not be launching alongside the 2016 update.
