I've said it in other posts, these imagers were rushed to market 2-5 years ahead of time simply to provide a new act for the special holiday performance of security theater.

If software is being rushed to provide another new act for security theater by April it it is because either: (1) TSA is afraid they will lose in court on the virtual strip-search aspects of the fourth ammendment argument or (2) TSA is receiving an enormous amount of behind-the-scenes pressure from congressman et. al. over the looking at nude images issue or (3) a combination of both.
