Nope - at least not that I'm aware. From my understanding, we are in Depp's team's part of the trial, and right now they are showing recorded depositions, some that Heard's team took as part of their defense. Depp's team has the option of showing them up front rather than wait until her team's part of the trial. I don't know how many of these recorded depositions there are, nor if there are more live witnesses to be called by Depp's team. Witnesses can be recalled too.
Depp was on the stand 4 days: he gave testimony, was cross-examined by Heard's team, then his team responded to the cross examination. I imagine it will be the same for Amber. The progression so far to my experience in this part of the trial has been character, personal and psychological testimony, then criminal/police testimony, now they seem to be focusing on the actual defamation/career impact testimony with agent, lawyer and ACLU testimony.
