And the most credible rumor is that their never will be, as that is already out-dated tech. They are skipping to a
lawnmower bot. I remember seeing that tech at Disney Epcot 15 years ago, and knew that's what I wanted someday. I'm sure Milwaukee could improve on the tech, and get more than an 8.7" cutting width, but still keep using the 18v battery. Though no matter the cutting width, if you aren't actually doing it, who really cares.
and that rumor, that was started here in this post. I really don't want to see a mower, unless it is a robot or a rider, and no 18v will be powering that monster (will just have to buy the Ryobi & give it a paint job). Reason being, is if they are taking time to design a mower, they took time away from something else I think would be more useful. I'm also becoming more & more against lawns, at least with the amount of investment they require for so little in return (fertilizer, weed killer, grub killer, water, gas/time and still mole problems no matter what). I'm hoping to convert a large section of grass to creeping sedum next year
