Yeah, these aren't custom-built cars - they're mass-produced figures, at the very least 500-700, most are well above that. Why can't they just judge demand (it's not like it's an unknown property,) manufacture accordingly, and then show/announce a figure 3-4 months before it's available?
Sideshow is carpet bombing its own support base with the quadruple killer of skyrocketing prices (above HT,) consistent QC/CS issues, a stream of re-releases of old "limited" stuff, and delays of well over 12 months between preview and in-hand (in some cases even re-releases are over a year.)
Who wants to see a figure then wait nearly a year and a half to get it?
What they don't understand is there's so much great stuff coming these days, you wait 18 months to deliver and your customer is no longer excited and has already blown the cash on something else.
