Don't expect it to be announced this year. The Star Wars hype would just drown it out instead of vice versa. Universal takes their time with announcements anyway. Everyone with an interest in this subject already knows what they're doing, so they obviously aren't compelled to say anything. The park could be half finished by the time they do.
They’ll wait about a year after Galaxy’s Edge opens to drop the big announcement, that’s my guess. Like a movie villain, they’re letting Disney have their fun now while they plot and wait in the shadows for the perfect time to strike.
But seriously, as for IP’s I’d like to see in this new park, I’d have to say
-Fantastic Beasts/1920’s America (for a third Potter gate- also disconnected from the train aka London)
-Dreamworks Land (Panda, Dragon, Madagascar, maybe Shrek and get rid of Shrek 4D at the Studios)
-No illumination (we have minions in USO and SLOP coming soon in Hollywood which I could see coming to Orlando too)
-Star Trek (sci-fi area)
-Universal Monster World (rumored for Beijing)
-MAYBE Middle Earth (fits with Fantasy theme)
-No Jurassic, keep it at IOA
-Back to the Future DeLorean Rollercoaster (unlikely but I can dream for them to revisit some of their still-popular classic films as they are still exciting IPs, see Kong).
-Maybe somehow make a Scooby or Spongebob ride for a kids area (still have access to HB and Nick, plus theres a new scooby animated film coming out in 2020).
