Looks like HASBRO is releasing their OWN Rey lightsaber, this one based on the filed down glass eye saber.

This one will probably be available in the big box stores, while the D23 saber will likely be a Disney stores exclusive.
I'm not a huge fan of the filed knurling on the TFA saber. I'd rather have the non-filed down version, which will probably be the same price as the Black Series saber.
