Remember I'm no longer quite the preterist I was. I've become a "Panmillenialist" -- it will all pan out in the end.
Basically, Revelation is not the only source of prophecy in the scriptures. Yeshua says things. There is plenty in the book of Daniel, Isaiah, Ezekial, etc.
In addition to that, let's consider what the REAL basics of believer's eschatology is: Don't lose hope -- God wins. Our Lord and Messiah will come again. Be ready.
MJ eschatology particulars is basically concerned with the role Israel is to play -- how the age of the gentiles has come to fullness and the age of the Jews is beginning, and how this hastens the return of the Messiah. Of this I'm absolutely convinced.
If you are truly curious about how eschatology can work differently than you are used to, you might get a lot out of reading what protestants had to say on this subject before rapture doctrine was formulated in the 1800's. Because my family was Wesleyan/Arminian fundamentalists, closely associated with the Church of the Nazarene, I grew up without any of that stuff. Here is a link on Wesley's eschatology, and a link to a pastor in the Church of the Nazarene writing about premillenialism:

Oh, and I am not advocating the Church of the Nazarene (although I like them very much) or Wesleyanism or Arminianism.

This is all pretty peripheral stuff for MJ. Some MJ's might agree with this, others not.
