I would highly doubt that it would include any other engines and I would strongly hope that it wouldn't. For me, at least in a product like CIS, I believe that multiple engines are incredibly unnecessary and a waste of both money and system resources.
I agree 100% Chiron. Generally multiple engines are an invitation for both wasted resources and
potential conflict. The current balance of detection and proactive defense such as sandbox, defense+
in my opinion is just right and is more than sufficient for most users, novice or advanced.
