I've read somewhere the first names are different.
They are, physically, 2 different people though... Plus, unless he's capable of stopping aging, they can't be the same guy regardless of even what LFL may say. Hair color was even different (but not GREY like one would think it would be after 20 years or more).
I am going with different guys even if Lucas himself came out and said otherwise. Screw him and his jiggly neck flab.
Oh, and ANH Antilles has no scars... Cosmetic surgery must've been on his priority list I guess.
EDIT: out of curiosity I didn't see a databank entry for him on the official site. Was curious about any backstory they had maybe, but at this point I'm guessing that LFL just isn't talking so Hasbro will be left with little information...
I'm sticking to my guns on this, the figure sucks, and that ain't the dude in ANH...
