That's the irony - it's MUCH cheaper to produce digitally, 
so I'm not sure what costs they'd defray with the traditional 
method, which is more expensive.... ?
And I don't think I'd call it CG - I think CG tends to refer 
to 3D rendering more, while "digital painting" (i.e. digital 
anime/production) is the seamless painting we're talking 
about...
