Successor of Maybach?

Hello, the Maybach is now technically quite of the day before yesterday, compared to the W221. Is there a new edition planned, or at least a model maintenance? Or is the car bought so little that a change is no longer worth it? Maybe even its end in sight? Questions about questions. Are there insiders here who have concrete facts knowledge? Would be grateful for answers that are not based on mere conjectures. MFG Pluto
