I had this long post thought out with a variety of WDW strategies to even out the crowds and/or wait times for attractions (you know the ones - free dining, reduced ride throughput, expanded party and/or festival dates, etc. etc.) and the inevitable eventuality that summer crowds creep back up or exceed the past after folks get a taste of crowds outside of the summer.
Long story short, I'm thinking "crazy busy" is the new normal for WDW now and for the foreseeable future.
