He'd have 2 years $84M left and Year 3 is a player option, so he can opt out after next year too if he wants. He holds the cards. I guess if someone wants to give him 5 years $150M with more opts outs, then he'd consider it - especially if he hates it on the Mets.
Power is down again this year. IMO, he needs to keep his ISO over .160 to remain a star. Long term deals for Bo remain quite risky. What a comeback story it would be for him to return and help turn this team around. Tony Fernandez like stuff maybe?
