So what that prophecy is saying is: a pope will sit on the throne of Peter who. Having made that clean (and by that made fools of those thousands who believed and still believe "Peter the Roman" to be a code name for the last pope) let us do some hunting for the identity of the next. Ouellet, 68 years old, is a veteran in dealing with the secularized West, someone smart, intellectual and cosmopolitan. He is close to Benedict16 in theological thinking and someone who could bring a strong hand to the Vatican bureaucracy. Malachi predicted in code-manner all future popes with some formidable accuracy making only few mistakes. Now, after the resignation of Benedict16 there remains in his list one more future pope to be elected.
As you can see, in this so-called Malachi prophecy there is no "Petrus Romanus" given as a code name for the last pope coming after Benedict16 as written about in many books on that subject; there is no "Peter the Roman" in that prophesy, there is mentioned the "Roman Peter" but it is not given as a.
