I don't think reservation availability this far out is a good indicator of how crowded things will be. We were supposed to go in early February. At about 46 days out, there was availability at many restaurants for ADRs. Two weeks later, none at all for popular places. We wanted to check in at Disney 1 night early. There was availability for Pop Century also at 46 days out. A week later, the only value resort that had availability for that night was AS Sports in the preferred section but that didn't last long.
Further evidence: Due to medical issues, we changed our reservation to April 7th- crowd levels 7&8. (Can't wait!) Even at 80 days out, there were ADRs available for CRT, Chef Mickey's, Le Cellier at lunch, and Ohana. There were even Fantasmic Packages available a few days ago.
That said, my friend went for her first visit in September last year and said the longest she waited was 20 minutes for anything.
