Nekobat is right.http://cryptozoic.com/articles/mark-date-dc-crisis-expansion...
Look closely at the picture of the Super Hero cards at that link. The new Heroes just say Super Hero, but the revamped heroes from the original game say CRISIS Super Hero.
The Crisis Super Hero cards have different abilities designed for co-operative play. The Can't be used with HU without the Crises cards just like the old set because they aren't the same cards as the original set. Crisis Expansion is designed to make DC DBG have team play similar to the Marvel Legendary DBG.
Also, this is Crisis Expansion Pack 1. There is a real good chance that Crisis Expansion Pack 2 will be released sometime next year with more new heroes and revamped Team-based versions of the eight HU heroes.
