What did you EXPECT him to say???
"Uhhh, we really wanted to use Touch ID, but we couldn't figure out how to make it work under the screen in time to launch it this year so we're giving you the only alternative we could get to work in such a short time: Face ID"???
Of COURSE they are going to try and hype Face ID. They'd be idiotic not to. It's the security feature they had to use on their flagship phone.
And yes, they "had to". They didn't "want to" no matter how badly Mr. "I lost my ability to design somewhere around October of 2011" Ive wants to try and sell it. They wanted to integrate Touch ID under the OLED screen. That would have been cutting edge. That was (documented) what they wanted to do.
They failed.
Face ID will be fine, but the rhetoric that it was always their first choice is patently silly. Would you rather have Face ID (and all of it's potential issues, even if none of them come to pass) or Touch ID integrated under the screen? Taking up NONE of your front real estate and using technology that has been rock solid for years...
Anyone that says Face ID is being dishonest. It will work, and it'll probably be just as convenient, but it was a "last resort" and absolutely is the consolation prize we got so they could get the X to market this year.
