Maybe it was too early to rejoice then.
But even if openly denying something that will happen seems to be the new default position for PR these days...
The only thing that makes it plausible that Smith was at least approached was his recent album and Grammy success. Although, despite a slight parallel to Adele´s career trajectory (she was much more successful, by the way), I don´t think winning a Grammy has ever been the deciding factor for any artist to be asked to contribute the next Bond song.
Also, Smith´s recent vocal cord problems could also have been the reason for not considering him or for him dropping out.
I still believe it will be someone else.
