Universal Studios in Florida have called a press conference for 1st August to make an "Epic" (their words) announcement. It seems highly likely they will announce the building of a new theme park at their Florida complex. Construction has been underway in a vacant block of land for some time and I guess their timing is set to steal some of the thunder from Disney's expected announcements at D23 later in August.
Rumours of the new park include another Harry Potter universe land - this time based on Fantastic Beasts series, as well as a Nintendo-based land.
I'll guess we'll know in a couple of days time!
