The front hair detailing makes me think new. It looks better, it looks taller even. But the temples, the very sides of the face and forehead make me think of DX13. Is it just a modified DX13 with some improvements but some old flaws not corrected? Or a brand new sculpt which happens to bring some improvements but repeats some old flaws. I dunno...Not sure if that HS is truly new.
It looks like the DX13 to me.
