YEah IF Beccky leaves for Tony Con's AEW, it'll be a big coup for sure but you have too many variables right now that might now make it happen.
You have to wonder, did WWE really wait this long to re-sign her or was it something that Becky was demanding that held up those negotiations, or are they both (Becky/WWE) playing it close to the vest and just saying it's not finalized. With Seth re-signing it would make sense for her to stay.
AEW is still negotiating a new deal with WB and that might play a big factor in attempting to lure her away $$ wise. I'm sure both companies will be presenting her with crazy contract, but then that would make it a stupid move for AEW after snoozing us with Mercedes Monet's debut and I don't think she'd care about someone like Becky swooping in taking her limelight so soon.
