News update:
Both Marcelo and Angel De Brito announced that in one of the upcoming rhythms there will be a change of rules. This change is only for that rhythm.
Some hints revealed during the last galas:
The change will happen once there are sixteen couples remaining, after the Merengue.
Apparently, we're going to have some sort of Face-off as couples will be divided in eight pairs that should perform one against the other, with the Jury saving one of the two couples of each pair at the end.
Couples could choose any rhythm to perform.
