WWE will hold the 2019 Royal Rumble at Chase Field in Phoenix, AZ. It's the first time that a baseball stadium ever has hosted a Royal Rumble.
The second annual women's Royal Rumble match is "an event that will be repeated in Phoenix." Meaning that the Women's Royal Rumble match is sticking around.
Like with all "Big Four" PPVs, there will be an NXT TakeOver special, Raw, and SmackDown in the days surrounding the Royal Rumble in Phoenix. The Talking Stick Resort Arena will host TakeOver on the 26th, Raw on the 28th, and Smackdown.
