Most of the Vixen line is only available with Duplex, and it's kind of a mixed bag as to what scopes have what reticle options. Here's the breakdown of reticle availability so far:

1-4x24: Duplex (illuminated)
1-6x24: Duplex, Mildot (illuminated)
1.5-6x42: Duplex (illuminated)
2-8x32: Duplex
2.5-10x50: German #4 (illuminated, side focus)
2.5-10x56: German #4 (illuminated, side focus)
3-12x40: Duplex
4-16x44: Duplex (side focus)
5-20x50: Duplex, Mildot (illuminated, side focus)
6-24x58: Duplex, Mildot (illuminated, side focus)

It's worth noting that the only illumination on the Duplex is the center dot, much like Swarovski's illuminated plex. I don't have any German #4 reticles here to check, but I assume it's the same.

I'm sure that, eventually, nearly the entire line will have all three reticle options, but that's speculation and I have no way to be sure. Time will tell, I suppose.
