It's a survival of the fittest thing really. Hit the pre-order mark, get made, don't make the mark, get deleted.
But I have to admit that it seems to be nearing a breaking point of sorts. There are just getting too many suggestions to be able to find what you are looking for, or for any chance of one's own suggestion to stand out...
And a lot seem to be just individual satisfying their own quirks, with little thought to larger commercial viability. (I mean, riot cops are pretty niche as is, but I'm surprised no-one has requested fez-wearing winged monkeys in waistcoats yet....

)
I just hope for the guys at Wargames Factory that the handfull of suggestions that may actually reach production pay back the effort (and expense) of administrating all those suggestions and their forums.
And I agree with Thorbjørn Nielsen, it might have been prudent of the WGF-crew to have install some kind of pre-selection to weed out the truly screwball and extreme niche requests. As it is now, they may be forced to do a rather strict cull somewhere in the coming months.
As an experiment in commercial approach and customer feedback, it is interesting to see, at least.
Some suggestions don't seem suitable for the large scale of plastic production, but might work for Eureka's 100 club... Maybe they could co-operate?
So, making a short answer long, I don't really expect the Riot cops to make the cut, but thought it worth/fun trying anyway.

Yeah, I've got the Offensive miniatures Riot Cops tagged as well. They're the fall-back plan in case the plastics don't make it.
