The Hasbro FX sabers are out already, in fact, they're already available on Ebay.

Let's not get "Licensed", and "acceptable" jumbled around when talking about the 501st, and The Rebel Legion...

"Movie Accurate" = "acceptable"

"Licensed" = "Licensed", that's all.

Although the Rubies stuff is licensed, They're just costume wear, it is not Movie accurate, so -Unacceptable

The MR stuff is Prop wear, pretty close to Movie Accurate, especially the Helmets.
The sabers aren't really made to be worn, but display pieces.
