Being a faithful Catholic is much more than attending a Latin Mass. The Novus Ordo mass does not reflect the Catholic Faith, especially regarding the seriousness of sin and the sacrifice of Our Lord being offered. I grew up in the Novus Ordo and it is not the Catholic faith it is a new religion centered around man. I can't see how anyone can be saved clinging to those errors anymore than any other heresy. On the other hand, attending a Latin Mass without holding and defending true doctrine, not putting our faith into practice everyday will not save a soul either.
