All right who done it

Specifically, the Omega Squad skin
Is anyone else confused about where the ears came from? Not a single representation of Veigar, in any of his skins that I've seen, have displayed his head as anything but an amalgamous blob of darkness, of varying clarity.
Seriously, why ears? Is he going to have ears added to previous/future skins in order to compensate for the discrepancy, or is the Omega Squad version going to be the only one to be able to hear the rest of the team?
