Found this after a quick google search;

More fear-mongering speculative drivel, which I would not have expected from national geographic. It makes a lot of assumptions and reads like a "what if" scenario gone wrong.
As far as if a hybrid actually does exist, I have no idea. All the google results are news articles along the same line, and the image results give me what look like burms and what I assume are rock pythons, but I'm not sure if any of these are actual crosses.
