Nope. Talked to a dealer about the Limited edition today. It's a completely different trans.
No antistall
No throttle link
No auto HDS
No Mid PTO
No Cruise Control
He didn't know if the loader rev up button thingy would be there, but he didn't think so. He described it as a mechanical HST, similar to what the standard L machines have. If I understood correctly you'd still have HST+ purely through the lever.
I don't know if this is a clean sheet design or Kubota finding a bunch of old parts in a warehouse somewhere, but it's very much not the same transmission as the existing model.
