Dana White vs his wife

That's more suitable for the PowerSlap

It is
confirmed now that the main event for UFC 300 will be revealed during the post-fight press conference of the UFC 298. Yeah, I think so too, that they haven't had confirmations in the backroom for who will be fighting. We'll find it out soon enough though.
Good to know. It's about time. The expectations are set so high that whatever fight will get announced, many people will get disappointed anyway. And there are limited options for high-profile fights. The most viable options are probably Adesanya Vs DPP, or Aspinall Vs Pereira.
Everyone wants the biggest UFC event of all time and Dana doesn’t even know if Conor will be able to fight by then or not.
He confirmed that McGregor will not fight until later this year (Autumn).
