For what it’s worth, DC originally marketed New 52 Superman as being “more alien”. I could see it being more of a take where Clark identifies as a Kryptonian like his Pre-Crisis take and doesn’t put much value in his human upbringing. Maybe they won’t even have him be raised by the Kents.
Spurrier’s Flash run seems to be a sales flop so maybe the plan is to do a new Absolute Flash book starring Wally while the “main” Flash book stars Barry.
