We'll reskin Tellarites as Dwarfs, and don't forget Ferengi all worship the Profits. Will need a Proud subclass of Fighter.Now this is a change I can get behind! Klingon fighter (bat'lath specialized!), Gorn monk, Vulcan wizard, Bajoran cleric (of the Profits of course) and a Ferengi rogue. That sounds like a D&D party for the ages. Although you'd have to add Dwarves to list because of their popularity. Also because of D&D and Lord of the Rings reasons!
But seriously, the next edition will eventually fill in any gaps in the Players handbook. Except there will still be no support for Warlords or Psionics worth mentioning. (Kirk is a Warlord.)
