The only thing I'm not sold on about this being the addition is the fact that the 163 * 13 is meters, not feet. A US-based park would not be creating press releases and advertising highlighting a new coaster's dimensions in meters, and therefore wouldn't be doing marketing teasers in meters, either.
Then again, it'd be totally on brand for Six Flags to have created these teasers based off of a quick glance at the stats and completely overlook the fact that it's in meters and not feet. So who knows.
