Am I correct in saying that any unsold tokens will be burned? I seem to recall seeing that somewhere but I can't now find it

Yes, they announced that one week ago here:
IMPORTANT UPDATE: We heard the community! It´s important for us to follow the advice of the community! All unsold tokens will be burned, and the same percentage of our pool will be burned to keep a fair ratio!
ahh, thank you very much. I was starting to think I was going crazy

that's a really fine decision in my opinion, it stops there from being an inflated supply presuming the ICO doesn't sell out
