As I understand it, the next prophetic event is Christ appears in the heavens where His Church meets Him in the air and He removes them to where He is (Resurrection of the Church saints). Then the anti-christ is revealed when he sets up a treaty with Israel which begins the 7year tribulation. At the end of the Tribulation, Christ returns (Second Coming), removing all unbelievers from the earth leaving only believers to enter the Millennium along with resurrecting the tribulation martyrs (and possibly OT Israel believers as well). Then Christ reigns on Earth from Jerusalem, providing perfect world conditions for 1,000 years dealing swiftly with any and all rebellion and/or crime (not that there will be much). During this time Satan is bound but released at the end of the Millennium. He then gathers those who, even though having lived in perfect world conditions are still not happy with the Lord, (showing us clearly evil begins within not from outward circumstances) and the war of Armageddon follows which is put down very swiftly and then comes the end with Satan being thrown into the Lake of Fire, the General resurrection and then this universe is destroyed and the everlasting universe is created.
That's a rough overview as I understand things when you put all the passages together.
I believe Isaiah saw the new earth on this earth (ie.Millennium earth) as it will be one of great peace and prosperity. I don't think he saw the eternal earth as I think how it is made will be different from how this one was made. The new eternal earth will have an in built "everlasting quality" (for lack of a better term) imo.
