Following the very recent release of the original Parasite Eve on the PSN, Parasite Eve II has been confirmed by Square Enix for release on the same network. No release date has been provided but one can assume that it will arrive before the release of the 3rd installment of the Parasite Eve series, The 3rd Birthday, which will see a US release on the 29th of March.
Thanks to Siliconera for the details.
