As of this date no one can predict with certainty as to what will be included in the comprehensive immigration reform bill. Your guess is as good as mine. Regardless, I would recommend consulting an immigration lawyer to at least get an opinion on your husband's case.
We cannot know yet if reform will help your husband. However, the process to bring him back will require the help of an attorney and proving that he was not involved with any gang.
The answer provided here is general in nature and does not take into account other factors that may need to be reviewed for a more precise answer. You should consult with an immigration attorney before taking any action. The answer here is not intended to create an attorney-client relationship.
The specifics of the reform are unknown at this time since no law has been passed yet. We will not know if it will help your husband until after passage.

I agree with my colleagues. However, while no one knows the specifics of the upcoming rules, it doesn't seem likely that the guidelines would provide a path for one with "a lifetime ban". Do discuss the specifics of your case with an experienced immigration attorney.
