NEOS does not refer to the late model fabric and late model logo second generation seats, Somewhere along the line someone mentioned a seat with the Late model logo was a Neos and since people seem to think the two are associated with one another.
The new logo zeta II you posted actually appears to be a type S.
NEOS only refers to the more reclined version of Zeta II
Edit: Also the red Zeta II you posted under type S isn't actually a type S. Normal or NEOS, impossible to tell from a front view of the seat.
