Somebody posted this summary on Reddit yesterday. I don't know where he gets his info but most of what he says (especially conditions of refusing to participate if you're staying in a Magic Band only testing resort) appears to match what we've heard before here.

1: MyMagic+ eligibility is being extended to all resort reservations.
Essentially, regardless of when your upcoming vacation is, you're going to get MagicBands. Now, you may or may not have access to customize them on Dec 4th or 5th, but you will get them.
Rules still apply: you will need to link the resort reservation to My Disney Experience before you can proceed with the MyMagic+ fun stuff.
There is no longer a "testing window" for resort guests, though MyMagic+ is still in testing. Resort guests (with only a handful of exceptions that if you were a part of you would be aware of) are now fully eligible for MyMagic+ and all the good stuff.
This will roll out some time in early December, for all reservations from April 1st on.
2: MagicBand only testing is rolling out to more resorts.
You may be aware that Pop Century guests are no longer receiving Key To The World cards in addition to their MagicBands. (If you were not aware, congratulations, you're all caught up.)
This policy of MagicBand-only testing is being expanded to the All Star collection of resorts in early December, and does not have an effective end date.
This policy will be eventually pushed out to all resorts, sooner rather than later.
Keep in mind: if you are someone who does not want to participate in MyMagic+ testing and would prefer to opt out and get a traditional KTTW card, that will not be possible at any hotel participating in this round of testing. If you do opt out (which you still can), you will be issued a demagnetized KTTW card. This card will not work at any FastPass+ kiosks or touch points, and will also not work at traditional FastPass kiosks. Essentially, if you opt out at Pop Century or the All Stars right now, you're opting out of all FastPasses period.
Additionally, if you are staying at any of these resorts, you will not be issued a KTTW card unless you opt out fully.
3: Guests who have participated in testing are fully encouraged to continue to use MyMagic+ features after their stay at a WDW resort.
According to the My Disney Experience FAQ: "If you participated in a MyMagic+ test on or after August 2, you have the ability to link park admission, make FastPass+ selections using My Disney Experience, touch to enter the parks, and touch to redeem FastPass+ selections with your existing MagicBand, regardless of whether you are staying at a Walt Disney World® Resort hotel."
The only exception to this, of course, is guests who stayed prior to August 2nd, or guests utilizing non-linkable park admission (typically, Disney-issued complimentary admission).
4: Walt Disney World Swan and Dolphin are now being included in a separate MyMagic+ test.
Guests staying at these resorts can participate in a modified version of FastPass+, but will not receive MagicBands and are unable to link their reservations to My Disney Experience at this time.
In order to participate in FastPass+, guests at these resorts will visit a Swan and Dolphin Service Center in the park they are visiting that day in order to set up their three experiences.
Swan and Dolphin are the only non-WDW owned and operated hotels participating in FastPass+ at this time.
If you have any questions about MyMagic+, MagicBands, FastPass+, or the like - feel free to ask!
