How long does it take to get toys for new characters?

I wouldn't know because I haven't bought a lot of MLP merch. I know that Tempest and the sea ponies had figures and plushies come out right when the movie did, and even before that. But I've no idea how soon it took for retailers to get toys for Maud or Starlight after they were first introduced. 

From what I'm seeing, the kirin from Sounds of Silence are already hugely popular. I'd love to see some decent figures for Autumn Blaze, and I'm sure a plushie of her would make an awesome gift for my niece too. Yet there's no mention of any upcoming toys for her anywhere.
