The one and only thing I will question is in the dual functionality. As a rule, non dedicated machinery does not do as efficient of a job as a dedicated piece. Similar to a backhoe/tractor compared to an excavator, or a snow plow on a pick up truck compared to a blade on a tractor made for pushing, or a hammer drill compared to a dedicated jack hammer for that matter. Dual functionality has it's place, I'm questioning at this time if it is wirth being the guinney pig....
Though I have not personally run an A series Bobcat, I have had several dedicated articulated loaders. (Cat 910, 930, 950, 966 and an atiquated dual fuel Hough International with a hand clutch.)
Because an articulated loader has hinge in the middle and each body section swings, the tires on each side roll over lawns without tearing, assuming the lawn is hard enough to support the 4 points of weight you are placing over it in the first place..
The A series Bobcats have hinges on each wheel and unless you turned while you were driving, there is a serious potential to wreck a lawn. Then there is the issue of a weaker axle/drive wheel assembly. With a knuckled axle shaft, you have a weak link in the U-joint/yoke combination. Weather the machine is locked in skid steer mode, or on wheel turn mode, the axle is still the weak link. And no matter weather the machine is wheeled turn or skid steer, those U-joints and hinge points are going to wear which could be alot of undo maintenance unless you really benefit by this concept. . Right now the concept is a little too new for me to consider, and honestly, I don't see any other manufacturers jumping on that bandwagon.
