The 1970 Missal was issued by the authority of Pope Paul VI and every Pope has the same authority to revise it. No new council is needed.
The Roman Missal promulgated by Paul VI is the ordinary expression of the 'Lex orandi' (Law of prayer) of the Catholic Church of the Latin rite. Nonetheless, the Roman Missal promulgated by St. Pius V and reissued by Bl. John XXIII is to be considered as an extraordinary expression of that same 'Lex orandi,' and must be given due honour for its venerable and ancient usage. These two expressions of the Church's Lex orandi will in no any way lead to a division in the Church's 'Lex credendi' (Law of belief). They are, in fact two usages of the one Roman rite.
The Bugnini liturgy is an arbitrary patchwork which does not meet the requirements of the Liturgical Constitution of the Second Vatican Council according to which all accidental innovations must spring organically from tradition and yield genuine spiritual benefit.
