Eldorado coupe/convertible should be a given.  Even if a 4-door coupe due to low demand of 2-doors, they have to do an Eldorado.  I could see Fleetwood and Seville for sedans, I can't imagine given the market's thirst for SUV's they'd have more than 2 sedans, one on the smaller side, one on the larger.

Part of the reason why the change back to names is that from a marketing standpoint, I'm guessing customers and most importantly, potential customers never understood what the current naming convention meant after nearly two decades and a course correction on the way. Meanwhile Lincoln who began with names, changed to a similar three-letter naming convention leading with "Mk" decided it didn't work either and added back Aviator and Continental and also created Nautilus and Corsair.   So like Navigator, the Escalade name predates and will outlive nameplates like XT5 and CTS. The big problem is what will they go to. Some people want Cadillac to return to their old names but that may not make sense in the modern era either. And the transition to those names was made slowly over two decades as Cadillac went to a naming convention in 1936 that used spoken numbers that were spelled out...Series Sixty-Two, Series Seventy-Five, Sixty-Special (although Cadillac frequently also used "Series 62" and "Series 75" for shorthand in brochures). The name "Fleetwood" as attached to the Sixty Special and Seventy-Five beginning in 1941 with the demise of the custom coach business at Fleetwood body. The Coupe De Ville made its debut as a trim package in 1949 for the Series 62 the Sedan De Ville added a few years later and becoming their own models in 1958.   So the following names have been used over the decades for Cadillac cars (not counting the spelled out number models):   Fleetwood, Deville (Coupe, Sedan & Park Avenue), Calais, Eldorado, Seville. Brougham, Cimmaron, & Allante.   Can you see any of these names attached to a modern car? Maybe you could do a new Fleetwood but I'm not seeing any of the others come back.

I assume it will be a rebodied Panda Cross...
