I had my wife and son go through enrollment yesterday and I believe they got the new cards upon enrolling, though I can't be sure. It's definitely different than mine, though I've had mine 2+ years now. Their's have the machine readable infomation on the back (similar to passports) and more details (passport number, expiry, etc.) printed on the front. No hologram though.
Have they been already isuing these for new users, or could this actually be the 'replacement'?
