Any chance we will see the ships from wave 2 at Spiel, what ya think?

I'd say the chance is close to zero.

Heidelberger is responsible for everything FFG might show off at the fair, but usually they aren't too big on releasing new stuff there, and they have a very limited demo space anyway.

So I'd guess you definitely won't be able to buy the stuff there, and have a very low chance of seeing anything on display.

They had wave 2 on display at CVI but as for buying them I doubt it.
