Only Nintendo know exactly what was done when, they changed their story on the delay every six months or so.
They didn't do any development in that year?
As I recall, the first time apparently the game needed extra 'polishing'. By the time the Wii had been announced they just straight told us that they were delaying so they could release on the Wii.
Nintendo says they spent a year working on controls that would work for the Wii, which would indicate that the game must have been in a fully playable state on the Gamecube to start with, so we'll call it a year delay.
Peopele were pissed off then, people are pissed off with Rayman now.
