EverQuest Next Landmark Founder's Packs. Well, probably just one Founder's Pack, but you get the idea. SOE has updated its website with pre-order gifting functionality, and the company has also added a wee bit of extra incentive for current players of both EverQuest and EverQuest II.
That incentive takes the form of an in-game flag corresponding to your Settler, Explorer, or Trailblazer Founder's Pack purchase. You can either use the flag as a home decoration or "carry it along with you during your adventures in Norrath."
