It says 14 issues in the DC Universe app. With 25 pages per issue

That's a pretty thick trade

Thats somewhat of a thick read indeed but not as thick as some novels like collected volumes

Also new injustice issues and the animated movie announcement is cool but hope they drop news of when the next game is going to drop

Usually, trades are around 7 issues, so it's possible they split it up in two books. 14 issues is not unusual though and that'll be somewhere between a cm and a cm and a half thick, It's not that thick; compare it to some omnibuses which belong on a coffee table, or Showcase Presents which reads like a phone book.
