I doubt that. There will still be thefts of opportunity, and those types of thefts may well be easier to detect, recover and prosecute. They may even go down once in a while. Meanwhile, the pro thieves will just chuck those they can't unlock and unload. I would sort of assume that most of the pro thefts that happen in the U.S. go overseas anyway.
I too think it's just a matter of time, but not because of consumer pressure, or some wish to destroy credit cards. Those may be factors, but given the type of people I see shopping at Walmart, there's not going to be much in the way of "pressure" to convert. Eventually, perhaps, when they can find a solution that works for them and can deploy it to 11,000 plus stores in a reasonable timeframe, things will change.
