Not a lawyer, but I did dig into this. The issue at hand is that the lead designer of Lorca had worked at Upper Deck before changing companies, and there is a distinct possibility that he may have taken ideas for all upcoming game with him. Dunno if it will hold up, but it seems it may have enough merit that a settlement is likely.
I would absolutely believe this is some unreasonable or underhanded operation on Upper Deck's part. Neither Sean K Reynolds nor Patrick Sullivan had anything but horror stories from their time at that company.
