Wouldn't say it is a Specialized as it doesn't have the FSR Horst link back end, Specialized haven't done single pivot suspension frames so don't know what it could be.
looking at the specialized pics
could it be that this bike has a 3rd party swingarm
the official pics look the reverse of the bike in the photo
and join on frame looks different
