Longevity of the line
As to the longevity of this line (and in comparison to a line like WOS). While I think that many of the WOS comparisons are useless, this is particularly a comparison that does apply.
I don't think Palisades has to worry about keeping the general public happy. When Playmates first released WOS, the first series was packed unevenly, much like the first series of the Muppets. Homers and Barts were heavy - Lisa's and Grampa's were light (and Mr. Burns). The thought was the same as with series 1 of the Muppets - the general public will want more Kermits and Piggys that Dr. Teeth.
Here's the problem - the general public aren't going to buy these. Not in any real quantity, and not such that decisions on lines, pack outs or character selection should be dictated by them.
Playmates quickly realized that the Simpsons was NOT a general public line, but a collector line. They started packing everything evenly, knowing that most collectors wanted to buy one of each, even of the obscure characters. Yes, some characters last longer than others, but we have wave eight on the shelf right now, and if you can find much of anything before wave 7 hanging around, you're in the minority. Sell through on these continues to be very strong.
There's something else to keep in mind. Palisades is not a big company - it's not even close to the size of Playmates, and Playmates is far from a big company. They don't have to make hundreds of thousands of figures to sell. The runs can be much smaller than you'd expect, and a show like the Muppets has enough serious fans to support it. Hopefully.
Average figure runs in WOS are around 50k-60k per figure. For comparison sake, in it's heyday, any figure that McToys ran less than 120k of was an instant sell out. It's not quite that way today, but you see my point. Palisades is selling these through far fewer retailers, since TRU is the only major bricks and mortar retailer carrying them right now. I suspect that will change once they catch on, but with the size of the runs that Palisades must be doing, they should be able to do far lesser known characters and the large fan base will carry them through.
If Palisades manages this line well, it should be no trouble to see wave 10 and beyond. The single biggest mistake they can make is to try to appease both the general public and the collectors/fans. Doing so will end up not pleasing either in the long run, and will kill the line with retailers.
