1987-88 start date, but the same here. I had little hope that they'd go back to "magic-user", but "mage" is a good compromise.
'81 start date; I find magic-user to be too clunky. Mage or wizard both OK. If there will be multiple arcane spellcasting traditions (warlocks, sorcerers, etc), either Mage or Wizard could be the over-title, but Wizard has the most recent baggage from 3E and 4E.
Or maybe pick another term altogether ... Arcanist?
