I can't find either of these ships on amazon. I thought they were out already?

No. Some were sold as early pre-releases at GenCon, but that's it. They are not currently available in stores or online (unless you wanna go check eBay for inflated prices)

No only on GenCon. The rest of us must still wait until october.

Both are on the UK Amazon be sure not to look for outrider but yt2400.

Nope. Only available at GenCon or very inflated prices on Ebay.
