Line Developer???

I think “Mage: The Awakening” is the best of the three core lines in the World of Darkness. I like it since the beginning, at the hand of Bill Bridges, but I’ve grown much deeper feelings about it in the latest years since he’s leaving. Is there any one at White Wolf which we could call the line developer of Mage? I know all the latest books have a different developer but I think Ethan and Matt are the closest ones for line developer, am I right?

Why mage didn’t get any main developer when Bill bridges went out? Its seems to be working fine, the latest years have the best and most diverse material, so this is not an critic in any way. It’s just a curiosity.

Ethan currently handles all the lines that aren't Vampire, Exalted or Scion.
