I think they're using that as a marketing tactic. People would rather pay $50 for 1220 Platinum and an Excalibur Prime than for 1220 Platinum and a Lato or Skana Prime.

They may just have the Lato Prime and Skana Prime as incentive to upgrade further, just to have the set. They're not available to craft in-game, as far as I know.
