How do you think the timeline and status quo for Flash will be like once Rebirth is over? Unlike GL and Batman, it's the most butchered franchise of New 52 and editorial & WB has HUGE influence on the title due to DCEU and CWverse. How much of the pre-flashpoint can be salvaged?
Here's my two cents:
+ Jay will be reintroduced in a massive crossover, he will be dislocated from time and will have SF to give him immortality. Joan will be deaged the way Iris West was deaged in Final Crisis. His connections to Barry will be established fully, down to Barry naming himself after him after reading his comics. JSA will be an undercover metahuman group during WW2 instead of a simple predecessor of JLA.
+ Barry will start dating Iris again and at the end of Rebirth (2 years) he may even propose to her. This will be when Bart & Tornado Twins are reintroduced. COEI will exist and Barry's death will be reintegrated to continuity again.(it's dumb to erase the greatest comic book death anyway)
+ Wally's 13-14 when he first becomes KF. I hope they won't change it to 16 like Dick or I'll lose my s***. NTT didn't happen and he never quit superheroics or he faced his illness and that's it. He took part in new version of Judas Contract and knows Cyborg. When Barry dies at COEI, he tooks over but this time his Flash stint will be max 2 years. That's also when he met heroes like Kyle Rayner.
+ Wally and Linda won't get together right away and the kids are completely gone.
+ Rogues are changed completely back to pre-flashpoint (which is apparently happening at Rogues Reloaded). James Jesse exists and is currently part of FBI. Evan McCulloch may be reintroduced by killing Sam Scudder. Pied Piper breaks up from Singh and dons suit again, back to pre-flashpoint status quo. He was reformed during Wally's Flash tenure and their friendship is intact. Magenta still exists.
+ Thawne and Zolomon are lost in SF/timestream, the current Thawne is just a muppet created by Kadabra or Mr.Oz (which would explain why he was a mix of both). They will have a tag team at the end of Rebirth. OR Zolomon still exists and still a good guy (maybe never discharged from FBI) but his connection to time stream causes Psycho Pirate/Rebirth!Barry effect in his mind. Thawne may reach out to him to have a reverse version of Rebirth scene between Barry & Wally. This is pretty much wild card.
+ This is where things start to get murky: Bart Allen's status in Flashfamily while Wally Jr. also exists. This sorta depends on older Wally getting a book or not. If that happens, Bart has a chance over there. If it doesn't, younger Wally may be put on a bus?
+ I don't think Jesse Quick will be too young when she's introduced, considering Bart, Avery and Wally Jr. .She'll probably take more part in JSA book than Titans or Flash after being introduced.
+ Speed Force Tribes and Colonies: That's one of the biggest problems we have here. I believe we will get something earth shattering as Wonder Woman when it comes to this. New 52 Speed Force may turn out to be a lie created by Black Hole, so the whole deal with Lies will be applied to Dr.Selkirk adventures.
