I think GL is trying to fool us like he did on ROTJ
On the teaser trailer, anakins lightsabre glow doesnt look as good as obi's, but the closeup of him choking obi its lukes saber from ANH,
So what I'm thinking is that (sorry if this has already been said) ani uses his old one (blue) on the table fight and later somhow obi manages to take ani's lightsabre or ani just decides to put it away, and takes out his brand new sith lightsabre
no evidence for it, and all evidence against it can be written off as you stated.
so there's really nowhere to go with this...besides "it may happen...and it may not"
My prediction, most of the duel is blue Vs. blue. However, I have a feeling a short part of it will involve Anakin taking out another one and using red as well.
oh god, this has been discussed in about a thousand different threads, and it always ends up going nowhere.....i mean without some new concrete evidence, where else can it go?....(although i have to admit i've always seen the POSSIBILITY of things happening the way you describe).....even so - MEERGE!!....
have you watched the original trilogy dvds yet?....just posted the pics because some here didn't kow of the table duel....still can't see this thread going anywhere, wallalupp....he might change swords halfway through the duel, he might not....either one is feasable....end of story....for now....MERGE!!!....
