I don't think we'll be seeing an Easter Event here. The game is in closed beta so only the basic features are available, they're likely working on other game features and events aren't something they would focus on at this point in development.
I would be pleasantly surprised if we get one. But I doubt it. I guess we should keep an eye on the announcements area.
I personally agree with ThePhantom. It wouldn't exactly be a good use of the developer's time to focus on drafting and coding a temporary event at this time in the game's development when the goal currently is long-term stability and bug-fixes. Maybe next year for the Easter event... maybe even later this year with a different holiday.
