Based on the image, it looks like we can expect a chocolate and whipped cream filling in the center of these cookies, if they become a reality. Commenters seem to be a bit skeptical of the flavor, perhaps because Mississippi mud pie is such a beloved dessert, which means high expectations. As many of them pointed out, Oreo already has a cookie with white cream and one with chocolate cream and simply putting both in one cookie doesn't make it Mississippi mud pie-flavored.
We understand where they're coming from with the apprehension, but at the same time, we're fairly certain the chocolate and "whipped cream" filling combo isn't going to be bad. And, you better believe we're going to try the new flavor out the minute we see it at the supermarket. Just add Mississippi mud pie to the growing list of rumored new Oreo flavors we're hoping become a reality. We reached out to Oreo for comment and will update this post as soon as we hear back.
