If any of you are interested in reading on these things, there is a whole study in catholicism called "eschatology" and it means, in greek, study of the end times. The Church Fathers, who were the direct descendants of the Apostles, wrote volumes and volumes on this subject and the church has declared that (on any topic) if the Church Fathers agree, then it is part of Tradition, i.e. infallible.
I suggest you get a book (I mentioned one in this tread already) which summarizes all the teachings of the church which are considered Tradition and you'll have a great idea of the general outline of what is to come. Then you can add all the various prophecies out there that may (or may not, depending on God's mercy) happen to 'fill in the gaps' from what we know from Apostolic times.
The point is that the end times should not be a mystery for catholics as Tradition has explained so much of this (in a general sense). But, the subject matter is often forgotten, so that many do not know the knowledge that exists and has been handed down.
