The resorts do stuff on Easter morning. In years past it's been either a candy scramble or an egg hunt, both are on the lawn and broken up into age groups. The deluxe resorts also have character meets (not sure about other resorts, we're only gone to the monorail resorts on Easter morning).
In EPCOT there's also a free egg hunt in the World Showcase Easter day at the United Kingdom pavilion, you have to sign up for a time slot.
Mr & Mrs Bunny also meet in MK, though I don't know if it's just Easter week.
A few TS places offer Easter brunch as well as a holiday menu for dinner.
Details won't be available until April. Disney is always slow with releasing Easter events for some reason.
We spent the last 2 Easter's in WDW and loved it. It's crowded, but the weather was great.
