So they’re gonna release new colors and new blades for more $$$

We don’t know. It depends on a lot of factors, such as how much are they willing to stray from Canon… as well as how often are they willing to refresh stock product versions with updated software. There is an orange lightsaber confirmed in the upcoming Canon game, Star Wars: Fallen Order, but no official confirmation of a teal lightsaber in Canon universe yet outside of rumors and speculation.

  • Orange and teal kybers will only require a new blade, but not a new hilt.
  • Any additional new kyber/blade color will probably require a new blade AND a new hilt
  • Any new kyber voice will absolutely require an updated holocron from Disney with new files.
