Crisis on Infinite Earths Predictions

With the upcoming Arrowverse crossover that will be happening soon, I thought that I would predict some of what might happen in the crossover based on information that I have and other that I thought that I would just guess in some way. We'll see if any of these wind up happening in the end or not.

• Earth-90 Barry Allen will be revealed to be alive, but will die during the crisis.
• The Linda Park of Earth-2 will appear and have some important role in it.
• It will be revealed what happened to Jessie Quick and the Earth-2 version of Harry Wells.
• No Gotham characters will appear, but there could be cameos from them playing other people in one of the universes here.
• Earth-1 Barry Allen will indeed go missing, but will be found early into the next part of The Flash.
• One of the Supergirl versions will die.
• Earth-2 Laurel Lance will die.
• Eobard Thawne will race Superman at some point.
• There will be only one earth after the crisis with people from all the other earths living on this one now instead of any others.
• The storyline from Legends of Tomorrow will largely be unaffected by any of this due to that show having not started airing its current season.
