Is Rev 21:10 what all those OT references are pointing to? If so, it is obviously literal. Even the physical dimensions are given. This is the "final state".
Revelation
21:9 And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife.
21:10 And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from God,
21:11 Having the glory of God: and her light [was] like unto a stone most precious, even like a jasper stone, clear as crystal;
21:12 And had a wall great and high, [and] had twelve gates, and at the gates twelve angels, and names written thereon, which are [the names] of the twelve tribes of the children of Israel:
21:13 On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
21:14 And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.
21:15 And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.
21:16 And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.
21:17 And he measured the wall thereof, an hundred [and] forty [and] four cubits, [according to] the measure of a man, that is, of the angel.
21:18 And the building of the wall of it was [of] jasper: and the city [was] pure gold, like unto clear glass.
21:19 And the foundations of the wall of the city [were] garnished with all manner of precious stones. The first foundation [was] jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald;
21:20 The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst.
21:21 And the twelve gates [were] twelve pearls; every several gate was of one pearl: and the street of the city [was] pure gold, as it were transparent glass.
21:22 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.
21:23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb [is] the light thereof.
21:24 And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it.
21:25 And the gates of it shall not be shut at all by day: for there shall be no night there.
21:26 And they shall bring the glory and honour of the nations into it.
21:27 And there shall in no wise enter into it any thing that defileth, neither [whatsoever] worketh abomination, or [maketh] a lie: but they which are written in the Lamb's book of life.
