Well, as if I have to state it, the IOC knows they have to change with the times. And it's mere nomenclature matters -- so no biggie.
(But here's the thing: I have an Greek acquaintance on FB who has a great collection of Olympic Games artifacts. He loves to claim that the 1906 Intercalated games are genuine Oly Games--a stance he takes since it was held in Athens, and of course, he is a die-hard Hellenic. However, the IOC over-ruled that notion long ago that 1906 breaks up the very neatly ordered time continuum of quadrennial celebrations, hence . . .)
BTW, for historians out there, I just received my digital copy of the latest Int'l Society of Olympic HIstorians journal and the issue topic & lead story is the Centennial marking of Chamonix 1924. So, if Nice-AF 2030 is crowned next year, then another Centennial marking (insofar as being named) also lines up very neatly for the French.
