Engadget is reporting the Google is talking to the U.S. carriers about buying Softcard, which is the only tap-and-pay option we have on WP. (Even if it doesn't work in all that many places.) Hope they don't pull a Youtube and screw us.
If they do then they will either have to continue support for WP or Microsoft will have a case to force the carriers to allow the native wallet app. If they don't there's an anticompetitive lawsuit waiting to happen.
