I wouldn't bet on (something)

I think it is very unlikely that something will happen or be the case. A: "John said he'd be here by 8." B: "Yeah, I wouldn't bet on it. John has never been on time for anything in his life." Politicians talk about reform all the time, but I wouldn't bet on any legislation coming out of Washington anytime soon. I would hope that the industry is moving towards a more customer-friendly position, but I wouldn't bet on it.
