sounds like he accepted the offer, and will possibly come over for camp and then based on his performance whether he stays or goes. chances are if he is headed for the echl or limited time on the phantoms that he will opt to go back.
There are some quotes of him where he says that he will stay with Lugano for 2007/08.
"Es ist klar, dass ich eines Tages in der NHL spielen möchte. Vorgängig habe ich aber dem HCL mein Wort gegegeben, dass ich zumindest in der Saison 2007/08 hier bleibe!"
Translation: It's clear, one day I want to play in the NHL. Urgently, I gave my promise to HC Lugano, that I will stay for the 2007/08 season.
