A:AnswerYes, any purchases associated with your Playstation ID will be available in your library to download again. Not sure about game saves though. That may be dependent on whether you use cloud saves.
A:AnswerNo one knows especially with the current situation. With the PS4, there were some available at the store for launch that weren't taken for preorders. But with 2020, retailers might just give them all to preorders to avoid long lines of people together for health reasons.
All-in-all tho, sony and retailers haven't said anything about this.
