Short Summary: I don't think it's ever going to get any better, only worse... :/
Yes, I can't say I disagree,
but when you look at the cost of them used,
especially FT-12, or all 3 together, they
still sell for more
used then that.
Also, since the non-toy FT-12 set is already sold out everywhere that has them up on their website, I doubt the reissue will do anything to lower that used price.
Could they do a reissue again later? Who knows, but when you look at overall pricing trends and the fact that Transformers have been around since '84 and are
still going strong, I don't think that trend is going change direction any time soon.
I also have very little faith that Takara will ever make them, or if they do, I'll be in a nursing home by the time they announce them. :/
