on point 1. Fieldens OOC this year and, in terms of player ranking, Hock ourweighs him considerably, so unless its because of something peculiar that's he's done, I don't see it coming to much for him.
Point 2. if that's true, Wigan will fire him to the moon. They were pretty strict with the hoops they made him jump through on his time off. If he's made a monkey of them by re-offending, they'll be livid. Plus, as you say, he won't be playing for anyone if the RFL get wind.
If points 1 and 2 aren't true, I'm not sure why he'd be moving, given what he brings on the pitch added to the personel that they're already losing for next season.
