At first I wasn't going to plan on getting this. I still *might not* - but that's looking more and more doubtful now.
Rebelscum had an article from FX-Sabers.com that spoke of a Yoda FX Saber in the works and also included the first in-person pictures of Obi-Wan's ROTS saber that I've seen. It looks far better than I thought it did in other images (ones MR took themselves for promotional purposes). And I'm hearing about rumors of possibly new sound effects!
Of course I'll shamelessly plug my desire for my favorite lightsaber of the entire saga: Obi-Wan's TPM saber from Episode One, but the E3-4 saber might very well turn out really good.
Hopefully at Comic Con I'll be able to see it in person.
