Recently Dieter Zetsche mentioned the fact that there are no plans concerning a new generation of Maybach cars.
During a last year Maybach closed 29 of 71 dealerships in USA. Reason - the cars are not wanted. Instead of planned 600 cars per a year dealers can hardly sell less than 150 cars each year.
It seems like Maybach will exist more 5-7 years being slightly modified and then will be slowly killed.
