Larians invests a lot in a new engine and ideas of character origins. It swallowed a lot of resources. I guess more than they expected. Unfortunately they overhaul almost all game mechanics (combat rule-set and item set) Current game-play status looks to me more like prototype or a collection of ideas than working game system.

Although they might be able release a game in a 3 months I would rather they postpone it to to Autumn to get time for polish (re-create) combat. Make arena alive, make it a playground for combat and item systems testing.
