OK, I couldn't find the new in english... so I'll have to translate it from Spanish to English. I'll post the translation first and the original new below it!
Translated new:
Nier will be turned into a saga
Announcements will be made at a later stage
With its European launch in the past month of April, Nier has become the sleeper hit of the market, and the plans are that it'll be turned into a saga.
Yosuke Saito, the highest man in charge of the first title, has assured japanese media that there are new projects based on this Intellectual Property already set in motion and that they'll, in fact, make an important announcement depending on how this year advances.
The first rumours point to a direct sequel to the series in the same consoles, that means, Xbox 360 and PlayStation 3. However, the possibility of them working on some sort of derived product cannot be discarded.
