Hello this is an interesting question and I have been thinking of how to respond to this. Actually, I feel the Sabbath will always remain, but I feel a feature will exist in the new Earth that did not exist before its’ establishment. In the Bible on one of Jesus Christ preaching tours a Samaritan woman asked him which place the right place was to worship God? Jesus answered:
John 4:21
Easy-to-Read Version
21 Jesus said, “Believe me, woman! The time is coming when you will not have to be in Jerusalem or on this mountain to worship the Father.
This is an interesting answer since the woman is concerned about the correct way to worship and she thought that a building was the proper place to assemble together and worship God. In today's world this is the only and common way that human's worship God. But the answer that Jesus gave the woman indicates something different about how God expects worship to be conducted on earth. Throughout history even in former times the place of worship has been the theme of religion and often decorated or simplified as a display of respect for divinity, that has been human nature since the founding of the world. The Bible has passages that show us the correct way to worship God regardless of a place that we go to offer service.

Many People Will Stop Loving God
3 Remember this: There are some terrible times coming in the last days. 5 They will go on pretending to be devoted to God, but they will refuse to let that “devotion” change the way they live. Stay away from these people!
So, the Sabbath had really never actually been observed on earth people have found ways to try and follow a time each week to devote themselves to honor God. Without the right heart condition and proper respect for divinity people cannot get the attention of God, who will in turn reject them. What happens in the New Earth?
Jeremiah 31:33-34

33 “In the future I will make this agreement with the people of Israel.” This message is from the Lord. “I will put my teachings in their minds, and I will write them on their hearts. I will be their God, and they will be my people. 34 People will not have to teach their neighbors and relatives to know the Lord, because all people, from the least important to the most important, will know me.” This message is from the Lord. “I will forgive them for the evil things they did. I will not remember their sins.”
