Randy Orton and The Usos are WWE lifers. Ziggler is a guy with no spine. I would absolutely believe Kairi could leave, because she has other options. More options exist now than ever have before. Stardom wants her and Io back because they want the female audience in Japan back for Stardom, and Stardom is going to make a BIG offer to her, and they can, since they're billionaires, and AEW will also make her a big offer and clearly AEW is much, much, much more Joshi friendly than WWE is, so if she wants an American platform that gets her name out there more than going back to Japan will, she can go there. She knows she has a ceiling on her career in WWE. Maybe she'll stay if WWE offers her a sacrilegious amount of money, to where it would be foolish of her to leave, regardless of how she's booked, but I don't see why she would want to stay in WWE otherwise. She's not going to succeed there even to the degree that Asuka has, because she isn't Asuka. No one is.I'm not sure, man. I guess we'll have to wait and see. In the past you could pretty much call the top 4-5 matches of Mania by about December, but it's not like that anymore, everything feels booked on the fly these days without a long term plan. Who would have thought this time last year that Kofi Kingston would be winning the WWE Title, or Roman Reigns would be wrestling period. I think Wyatt and Reigns is set, I can't see them strapping a rocket to Strowman, and there's nobody else really. I see Bayley and Banks too just with the constant reminders that "Sasha is the real star of the team" I see Bayley snapping and attacking her. Other than that I'm at a loss as to what happens. I suppose they teased Becky and Shayna strong, but with Shayna still being NXT champion and their tendency to forget things who even knows.
I wouldn't read to much into the Kairi Sane stuff, Meltzer has said similar stuff about Randy Orton, Dolph Ziggler and The Usos in recent years, and they are still around.
Ripley will beat Shayna at the next Takeover and Shayna will win the Rumble. Remember that Shayna is 39 years old, so she isn't going to be on NXT much longer. They love her and they want to get something out of her on the main roster. She's set for a rocket push. I can see Shayna defeating Becky at WrestleMania and that's where Ronda returns and costs Becky the title, setting up Ronda vs Becky at SummerSlam. That's why it didn't happen at Survivor Series, and they left that feud with no finish because Bayley lost, and had Becky get her heat back on Shayna to end the PPV.
As for Bayley and Sasha, if Charlotte has no plan, that feud WILL be sacrificed at her alter, because everything else is. If she has no plan, Vince is gonna say "GET CHARLOTTE IN THAT FUCKING MATCH NOW! I DON'T CARE IF BAYLEY AND SASHA MAKES MORE SENSE 1 on 1!"
