Yes, the 256 and probably in silver; although, I'm not as certain about the color as I was last year when I got the 7 Plus in Jet Black. I knew immediately, that was the color I wanted then. This year I'm not so certain. Like others, I'm disappointed about the delay, but I would rather be given these dates than be told it will ship in 6-8 weeks if I had pre-ordered this Friday. The delay is actually permitting me to upgrade my Apple Watch S0 to the non-LTE S3, which I wouldn't be doing now if I was getting the new iPhone now.
As for cost, my carrier financing plan will go up about $12/month, so it's not a big adjustment from what I currently pay.
