So here’s why I expect a CW show shakeup after COIE aside from talk they want a 10 year old Jon.

Batman on Earth-1 is and likely will remain a guy 20 years into his career.

Barry is 7 years into his career.

Superman needs to be somewhere between 8 and 21 years into his career and his relationship with Lois.

Why does Superman need to be a contemporary of Batman? Because it gives him a role to serve relative to Batwoman. If Bruce and Alfred are off limits, Clark’s the one who can come in and give feedback but only if he knew Bruce. Why older than Barry? Because Barry and Kara are contemporaries and also because you need Jon born back around the premiere of Arrow.

Probably around 12 years in minimum.

Sure, you can have slow aging but overall, I think Superman and Lois need to be 40 in the eyes of the public based on how the Arrowverse is setup.
