Nope.
S&W doesn't share their roadmap for future products. We usually hear nothing about new guns until they appear on the website or are shipped to dealers that start showing them to customers before the official release date. They make no effort to time new product introductions for big trade shows like SHOT so their new guns get introduced when they are ready throughout the year.
A good example is the small, single action, metal framed CSX. Not a single rumor or leak until someone took a picture of the gun their dealer showed them and posted it on reddit. That's pretty typical for S&W.
S&W seems to have decided having a hinged trigger instead of one with a blade is costing them sales so it is likely all new guns will not have a hinged trigger. And with OR pistols becoming increasingly popular there will probably be more of them in the M&P line. But that is speculation on my part.
