The timing is certainly interesting. The deal, for which rumors had been floating around this weekend, was announced this morning, the day after Wrestlemania, which - for storylines, anyway - is largely considered to be like a 'season finale'; the "Raw" after 'Mania is typically treated as a reset - new storylines start, NXT call-ups make their debut, and the build to the next 'Mania starts all over again. It'll be interesting to see how news of the deal breaking affects locker room/backstage morale and, ultimately, what we see on TV.
One potential upside is that the deal appears to allow WWE to continue operating much as it has been, similar to how UFC functions under Endeavor; Nick Khan remains President, and (presumably) Paul "HHH" Levesque remains in charge of talent & creative. What remains to be seen is how the sale will affect WWE's clearances with NBCUni & Fox, particularly w/r/t "premium live events" (nee PPV, like 'Mania) airing on Peacock for no upcharge vs. UFC's $80-90 upcharge ON TOP OF an ESPN+ subscription. (If Endeavor follows the UFC model, they're going to lose a big chunk of WWE's PPV audience; that audience has had access for $9.99/mo (when WWE Network was its own OTT service), then $5.99/mo with ads under Peacock - you can't then say the same level of access is going to cost upwards of $100/mo - especially in this economy.
One definite upside of the Endeavor sale is that it means the rumors of WWE selling to the Saudis were just that. Had that deal come to pass, a number of high-profile talents (including the new Undisputed Tag Team Champions, Sami Zayn & Kevin Owens) would likely have walked away from the company, and it would have prevented others (Bryan Danielson?) from returning at some point.

Have a nice day!
