I remember Jeremy had issues with a landing page when people where searching for an airport. The airport wanted the domain. That was less of a black & white issue.
Personally I would find it difficult having to give up a site over a little legal issue & Its not as if I had the money to challenge it in court and if I did I wouldnt fancy my chances of winning.
They are great domains, thats for sure. If I was you NPG I would hold on to them & try to get as many sign ups as I could. If poker.com decide they want them, just write it off. I think you could get more off the sign ups than someone would be willing to pay by taking the risk on buying the domains
