All images are already lazy-loaded by all browsers, and in terms of memory usage they are only loaded in to memory per layout. However the layout-by-layout loading only works with entire sprites, so either all a sprite's animations are loaded in to memory, or none of them. Perhaps breaking your animations up across different objects would help with that.
Note in r133 the spritesheet size is upped to 2048x2048 (but it still might use smaller sheets to save memory).
