sherpas sorta upped the ante with All.I.Can so i guess those who have the financial security to do two year projects wants to try to see what they can accomplish.
but it's probably just a phase, like the person above me said - smaller companies have to do yearly movies to have a chance.
or is this the way it will be in the future? - either big, multiyear productions or short edits.. no inbetweens. time will tell.
