What will be email address format if top-level domain is .guru?

There is a popular website http://acloud.guru. I wonder what will be format of email address their employees will have?

I'm looking to get a domain from godaddy with top level domain as .guru. I'm confused what would be the email address I would get if I go for instance, http://apicture.guru? Is it xyz@apicture.guru or xyz@apicture.com
