Mag stripe needs to die anyways. It is such a glaring security issue, I openly welcome any effort towards getting rid if it.
Living in Canada, there's basically no instance where we'd swipe our credit cards, but they've still got mag stripes; and when I visit the US, I sometimes have to swipe my card, and it does work to do so.
I don't know about other countries, but a few days ago I got a new Visa card in France. It still has the magnetic stripe. I'm not sure if I've ever seen it used here, but a few years ago I think they were still in use in German gas stations (at least).
Some banks have a nice feature where they allow you to disable the magnetic strip of the card. I presume the information is still physically on the card, but they can somehow know that the payment was done that way and decline it.
