As far as the new heaven, I do not believe there is such a thing. I think you may be remembering some Bible verse foggily or something.
He’s speaking of the Resurrection.

Dogmas on the Resurrection
All the dead will rise again on the last day with their bodies (De fide).
The dead will rise again with the same bodies as they had on earth (De Fide).
The bodies of the Just will be re-modelled and transfigured to the pattern of the risen Christ (Sent. certa).
The bodies of the godless will rise again in incorruptibility and immortality, but they will not be transfigured.(Sent. certa)
Christ, on His second coming, will judge all men.(De fide).
The present world will be destroyed on the Last Day (Sent certa.) … Tertullian speaks of a world-conflagration in which, “the aged world and all its products will be consumed.” St Augustine stresses that the present world will not be entirely destroyed, but merely altered: “The form will pass away, but not the nature.” …
The present world will be restored on the Last Day (Sent. certa.)**
“The prophet Isaias foretells a new heaven and a new earth: “For behold I create new heavens and a new earth.” (65, 17; cf. 66, 22). He depicts the blessings of the new earth under the picture of world happiness (65, 17-25). Jesus speaks of the “regeneration,” that is, of the new formation of the world: “I say to you who have followed me, in the regeneration when the Son of Man shall sit on the seat of His majesty, you shall also sit on twelve seats judging the twelve tribes of Israel.” (Mt. 19,28). …
St. Augustine teaches that the properties of the future world will be just as suited to the immortal existence of the transfigured human body as were the properties of the corruptible existence to the mortal body (De civ. DeiXX 16).”… The end of the world and its renewal brings to a conclusion the work of Christ. All enemies of the Kingdom of God are now conquered, He surrenders the overlordship to God the Father, without however divesting Himself of the lordship and royal power founded in the Hypostatic Union. With the end of the world there begins the perfected Lordship of God which is the ultimate object of the whole Creation and the final meaning of all human history."
Sorry from veering from Subject. Just thought it was important to know that New Heaven and New Earth are dogmatic truths, albeit, little known.
Also … I think everything people have said regarding Satan’s inability to repent is right on the money.
I wanted to add one more thing: God took on human nature so that the reparation for our sins could take on infinite nature. Did God ever take on the nature of the Angels??? Don’t know. The essence of God is love, yes, but the essence of a spiritual being is not necessarily that of love. This brings up another interesting question: What is the essence of spiritual beings? Did the essence of the angels who passed God’s test permanently become love (to differeing degrees) and the essence of the fallen angels permanently become hate (to differing degrees). Do good angels share in the Divinity of Christ? Perhaps. Maybe the fallen angels can’t be redeemed because the act of their disobedience permanently changed their nature from that of love to that of hate. ???
Also, one priest told me that angels were tested for fidelity individually, making their culpability greater, while Man was tested as a race, making individual culpability lessened. Each individual angel sinned, while Man took on Original sin after the sins of our first parents… Maybe Man could be redeemed because he was born offensive to God, and therefore, his inherent badness wasn’t all his fault. Though born in original sin, Man also is born with inherent innocence before the Age of Reason. Perhaps this factor played a role in God having mercy on us. Maybe God loved the innocence of little children SO MUCH that He decided to have mercy on us.
Again, probably confusing myself more. Going to sleep now!
