He hasn't officially retired yet. He is currently working out in his native Sweden and if we had to believe his words, he'd only return to the NHL if the Stars and the Stars only, offer him a contract.
He retired after the season before last, only to be wooed yet again by the Stars. I think he'll just leave the door open, if he files the official retirement papers he can't come back for an entire year.
He has recently built a house down by the lake and he wants his kids to live in Sweden
He's been working out at home, and hasn't totally closed the door on hockey
a lot of speculation was that he was going to sign for Timrå in the SEL (2 hours drive away from here) because he was there and helped with some Stars players who were there this and trained this summer (Malhotra, Ott and others)
But it's been quite quiet on the Ulf front last couple of months - maybe he will sign for a team in time for the playoffs ? and leave the family home.
