I was waiting for the SE2. When that didn't happen, I upgraded from a 64 gig 6S to a 128 gig 6S. I'm almost always in range of a laptop computer, though. My son will be upgrading to my old 6S.
I think they hold the SE2 card for when they really need a new boost in sales. Like they did after the 6S release. Maybe next year we'll see a smaller, lower cost device, like the SE, to boost their sales.
