Disney is getting rid of KTTW cards from all resorts by January 20th. Here is a link to the rollout:

In addition, legacy Fastpass is scheduled to be removed from DHS and Epcot by the end of January so no more double dipping of fastpasses. It appears everything will be FP+ by the beginning of February.
I am a little confused. I thought originally we were going to be able to choose between MB and cards. I am a DVC owner and an AP holder. I have no desire to wear the MB and neither does my DH nor do we want to plan our vacation 60 days out (FP+). We decide what park we will be visiting at breakfast and then will only ride the rides with short wait times. It has worked for us for the last 7 to 8 years.
We have a trip planned for early May. Are you saying that by May we will be unable to get a KTTW card to open our room door as well as one for our AP instead of a Magic Band?
