I agree that he won't get his current wage for the reasons that you and Olly say. But, I still think he will be to expensive for the regions in the long term, with the 3.5 mill salary cap to consider as well. I probably shouldn't have used the term big offer, as that was misleading haha. As we've just seen with London Irish, Prem teams do have the resources to splash out (I am not comparing the player caliber!).
I'm not comparing Henson as a player really, I think the point I was making is that players have been through controversies through drink or drugs and teams will still invest in players. One of Phillip's lowest moments was the run in with the bouncer, but he still managed to get a large contract following this. Perhaps his form was better, but then he has recently had a decent Lions tour, albeit playing Gatland's way, so it depends on how teams might want to play.
