Colour nightvision for battery spotlights

I know that colour nightvision is now available on wired cameras but does anyone know if this feature is coming to the battery cameras? It is just at the moment I have a battery spotlight cam in the front garden because of the difficulty of having to wire one in with the location I wanted it in and although it can see right up to the garden wall with the light on as soon as it switches to regular nightvision I lose vision of half the front garden. I don't really want to leave the light on as I would think this would drain the battery really quickly. Anyone know if this feature will be coming to the battery cams?
