>This is 'Buscametales', the new spin off of 'La casa de papel' that Netflix is already preparing, starring Fernando Cayo and which recovers Álvaro Morte as The Professor

This is from a Spanish magazine but I don't know how accurate it is. Basically says that Tamayo will be searching for the gold that disappeared. The magazine says that it will be from Tamayo's POV.

This magazine was released on April 15, long before the announcement, and the stuff that we saw in the trailer line up with what was in the magazine post.
