Just as an addendum, the one thing I have come away with from preterism is that the Roman destruction of the Temple was at least a
partial fulfillment of the Second Coming of Christ but not the culmination.
That culmination and the end of the age is yet to come.
And yes, I would say that in answer to the Scripture :
Matthew 16:28 Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
Is partially fullfilled in the events of Acts chapter 2 when the Apostles were filled with the Holy Spirit on the day of Pentecost. The word "some" in Matthew 16 is tis limits the number in the sense of selectivity such as :"certain ones" i.e. "There are certain ones standing here which shall not taste of death til...".
Not all "saw" the cloven tongues and heard the mighty rushing wind only certain ones in the house "and it filled all the house where they were sitting".
The Day of Penetecost and the filling of the Holy Spirit being the first "sign" of the coming of His kingdom (Jesus Christ).
Then in AD70 there was certain and undeniable cessation of biblical Judaism (as opposed to Talmudic Judaism) and its required ritual of maintenance with the destruction of the Temple which lies in ruin to this very day awaiting the fulfillment of "the times of the Gentiles".
Why the wait until AD70?
Because:
Acts 13:46 Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles.
Along with that as Tom has shown, AD70 brought the death of the then primary persecutors of Christendom, the leadership of biblical Judaism.
Granted it was not long before the Gentiles (Roman Caesars) took up the mantle of persecution of the earthly manifestation of the kingdom of God,
the Church(es) of God.
