Okay, here we go...this is how it works.
Firebaugh has been playing again, and engineering-wise likes this new approach to floating the arm, hence the new look of the ball, or half ball now. Not sure if the change is engineering only or if there is also sonic improvement. So that's how all the new balls and arm tubes will be shipped. For the mkii you'll get that, with all tables having only the ltd arm. For we Originals, if you want to retrofit, we'll keep our suspension and arm rest pillars. You'll get the new ball and arm tube, that's all.
As someone said, the holes are too big on the original. And don't start thinking of drilling a small hole.
So that's it, in a poorly worded nutshell.
