In my opinion, Luke-Jr is a scammer himself, who only "accepted" the "Luke Unit" in a deliberate attempt to shill for BFL and rig the bet.
I would not be surprised, this is why the bet should have specified X forums members, perhaps using 1 of those preorder lists and stating must be confirmed by 1 of the first 25 people. Still then you have to worry that the 25 people will collude, bet against BFL delivering and then lie if the package is delivered in time.
The "Luke Unit" was not one of the three units the bet specified, so even if they had "shipped" it, it didn't qualify.
Thats an interesting, I shall query this further with some of the people in questions (just incase this is more than a mere bet being canceled due to conflicting descriptions).
I feel the site operators decision to nullify the bet due to a conflicting title and description was the right one, but the timing of when it was done was just plain lousy.
