I'm thinking that it's not a refurb.
Late to post due to pending other conflicts regarding timing.
Time will tell.
We're already keeping our fingers crossed the Seasons of the Force starts AFTER we have been so the crowds aren't ramped up by loads of Sheldons and Leonards....
I had the same issue with our January trip. I couldn't find any Fantasmic dining options for our trip, and I was thinking the same as you. However, last month, they suddenly became available, and there was lots of availability. Maybe they didn't actually open up those reservations until later for some reason? I hope that maybe this will be the same for you. Good luck!
