Yes they are indeed something new. They use differential pressure data on a network of pressure ports to infer flow direction as well as total and static pressure 9hence airspeed and altitude). The probe body is itself fixed, though, so they don't have inherent high angle capability in the way a swivelling head might appear to - though even a swivel has to have stops beyond which it can't travel.
(Edit - ignore remark about static.
Other manufacturers apparently integrate that ...)
