Point taken but I still fail to see how a total 64 bit pipeline has any benefit until one gets to the render stage. Textures for movie resolution model aren't close to the size that DAZ ones are - a lot of that stuff is procedurally generated anyway. Sure, the geometry and texture file sizes are heavy, but most of the other things (poses, mat file et.al) will prolly not see much benefit. Maya's 64 bitness mostly exists in mental ray, not the modelling / animation part.
