The extra long wheelbase XWB S-Class (X222) debuts in May of 2014, and probably with V12. The XWB S-Class is longer than the long wheelbase LWB S-Class (V222) but shorter than the ultra long wheelbase S-Class Pullman (VV222). 
The Mercedes OM424 V12 celebrates its 30th anniversary today (see a pic just a few posts above this one).
