I think alot of people grew too impatient waiting for more figures to come out. When it takes that long between figures, completists give up and sell off what they already have. I will never sell off my figures even if I don't get anymore. I love the ones I have.
As far as I'm concerned, lack of proper attention to this line is what killed it, not the fans. The fans sure ate up that Beserker, so there's still LotR interest out there.
I don't see how impatience would force 1:6 scale LOTR collectors to not want to buy a great collectible of a major character, I would think they would buy it wither it came out last year or will next year. I for instance have all the Colonial Marines, and I'd very eagerly buy up any new Colonial Marine characters if HT made them, regardless that they're produced 3 years late. But I guess that's just me.
The Beserker is a higher end statue, which attracts a very different sort of collector if you ask me. I can imagine all the LOTR statue collectors wanting to add it to their already large LOTR statue collection, without there being a need to have scale continuity.
