i talked to Peter Molyneux at E3 this year, and the first thing i asked him about was Unity. he told me they were hoping to have it playable at E3 05.
seems like there's gonna be some more waiting. but after seeing footage where the game goes from a 3D to 2D perspective, and just the most recent build, Minter can take all the time he wants with it. that game is gonna be special.
