What he is really saying that OoT is believed to be the first Zelda game if ZSS is not included. He was carefuly enough to choose wording so that he does not confirm something that is likely false, even if it is right, he will not confirm it.
In my opinoin, no timeline makes sence unless FSA is somewere before ALttP. But a good theory. It is just that I hate everyone asuming that Link from MC, FS, and FSA are the same person.
