The target audience for 5e is every player who isn't absolutely in love with, and married to, whatever game they're currently playing is, and is willing to try something new(ish).
This includes my group. Over the years we've played successful 3e, 4e, and now AD&D campaigns (with some Savage Worlds and M&M thrown in). We like (love?) role-playing games, but aren't partisans, loyalists, "Pathfinder men", "OSR-or-die", or anything like that. We *do* have a preferred play style, but that's proven to be system-independent.
