T-14 Armata and Kurganetz 25 in production or not?

According to a article in the ESUT they refer to a british defence newspaper which quoted Yuri Borisov who claimed that neither the T14 Armata or the Kurganetz 25 is in production, without giving any reason why.

Is that true? Anyone knows more about that?
