What are naming possibilities for other Eeveelutions?

So as we all know in order to evolve Eevee into a certain Eeveelution you can use the naming trick to do so. With Pyro being Flareon, Rainy being Vaporeon, and Sparky being Jolteon. In the Jhoto update, they decided to keep this tradition by having your Eevee be named Sakura to become Espeon and Tamao to be Umbreon.

So that got me wondering, when they decide to release the other Eeveelutions(Leafeon, Glacion and Sylveon), what kind of naming trick would they give to guarantee that specific Eeveelution? I would imagine Glacion being Frosty but there are way better names to come up with. So what are your ideas?
