If the 74 day FP+ window (as has been reported) is truly a test and not a 'glitch' in the system, they could be setting up for something like this:
90 days out, Concierge FP+, like it is today.
74 days out guests staying in a Disney resort.
60 days out, good neighbor hotels
30 days out, everyone else.
Now, there will likely be paid options for more FP+ or 'Express Passes' available for Disney resort guests, but the above is inline with what has been reported over the last couple of weeks.
Just some random thoughts, probably way off base, but who knows at this point.
I still wish they would go to a day by day system for obtaining FPs, but that will never happen.
