They're still the same cigar with the same blend. Changes in taste may be attributed to newer tobacco crops.
Oliva used to make a cigar for Erik Espinosa & Eddie Ortega (United Tobacco / EO Cigars). The brand was simply called 'X'. Due to similarities with 'Opus X', the Fuentes built a case and killed the brand.
We (Famous) picked up those cigars and re-packaged them. The rumor goes that they were re-banded as N3Ks. We can live with the rumor but that doesn't mean it's true.
