My two cents: Robert's above link to the "new Mass formulary for a Mass of the New Evangelization" has no verses for the introit, and also lacks an offertory proper and gradual. Thus the introit, although in style similar to an introit from the GR, is actually just a chant setting of a Missal-style text. If this Mass formulary were to appear in the GR sometime, it would likely have completely different propers, since the Missal propers and Graduale Romanum propers don't usually match.
