Preston removes the old heavens and earth in 70ad as do most Preterists. What he does not tell you is that he places ALL in the New Heavens and Earth. According to his view, along with the FINAL dissolution of the present heavens and earth, the judgment of ungodly men also sees its FINAL dissolution in 70ad.

(On Matthew 24:36)"We believe we have shown that in Matthew 24:36, when Jesus said "But of that day and hour knoweth no man," that his reference was to "that day" that would climax "those days" leading up to the final dissolution of the Old Heaven and Earth of Israel at the return of Messiah in 70 AD." (Those Days - vs - That Day)
