Taking away one digit from the CAP doesn't change much about the economy, so you just have to think logically about it in the face of two different accounts. I think it makes more sense that they would take away 1 digit from everything.. not to mention if you read the translation from Rein, you can see the article isn't just making one tiny mention of it that he could have mistranslated, the entire thing is almost solely about the balancing of money in the FFXIV 2.0 economy.

Edit: That isn't to say they won't be ALSO moving the cap down, just for the record. I'd assume both are in fact correct.
