No iFett, it's a completely different sculpt...
It appears to have torso articulation to it, and I believe there's ball/socket ankles there, whereas the original had neither... Not to mention the original has a molded-on earring, molded-on wrist restraints, and also this one's jaw appears to open/close whereas the original one does not.
I do believe this one would make a great base for a new ROTJ one, as rumored. I don't know if the saddle and all that is molded onto it though. Tough to tell.
