Seeing is believing.
My preference would be for a neo-Tridentine Missal adapted for popular participation and chant.
The old Missal had many beautiful prayers that would be more edifying to the faithful if they were in the vernacular and said aloud.
That said, I think it would be edifying to the faithful even if they could hear all of the prayers in Latin and be able to follow. I'm not saying that the prayers can't be said sotto voce (Trent anathemized that sentiment anyways), I'm saying that it may be prudent to not say the prayers sotto voce.
When 8 students from my Newman Club went to a Tridentine Latin Mass in the area, the biggest criticism was that they couldn't hear the prayers. They were fine with kneeling and receiving Communion on the tongue (even in a church that had no altar rails), as well as with the Latin prayers and chant and Latin/English Missals even though it was drastically different from what they were used to. To quote one of my friends: "the prayers were beautiful, if only we could hear them."
I have heard mention of a "Benedictine Rite" that would eventually evolve (this may be more wishful thinking than anything else). However, suppose the Holy Father would like to see a development in which the Tridentine Mass and the Novus Ordo eventually merge (giving a Benedictine Rite). I have seen blogs proposing that the Litury of the Word should be in the vernacular but much more august as is now being done by Vox Clara. Then, suppose that the Liturgy of the Eucharist would be in Latin so that it would be comprehensible to anyone, anywhere. Or, suppose in the "Benedictine Rite," many of the prayers said by the priest alone could be said (or chanted) in Latin. I am thinking of the Confiteor, the Pater Noster, etc.
It would seem the long term is to see an evolution which is beautiful and not an imposition which is ugly. The Ambrosian Rite and others still exist so it is not mandatory that there be only one Rite.
