Is the Siren Series Returning to PlayStation 4?

A Romanian press release says it is.

Update: Sony has responded to IGN's inquiry on the Siren listing. Unfortunately, it doesn't seem that a new Siren is en route, after all.

The listing for Siren was a mistake, it should have listed Rime. Siren was the working title name for Rime prior to its announcement at Gamescom 2013.

Rime is the PS4 adventure game revealed this past summer.
The original story is below.
Do you remember the Siren series? The PlayStation-owned survival horror franchise debuted in Japan on PS2 in 2003, and was followed-up Siren 2 on PS2 in 2006 and Siren: Blood Curse on PS3 in 2008. Ever since then, the series went quiet as the developer that made it – Japan Studio sub-team Project Siren – went on to work on the PS Vita title Gravity Rush.
But a Romanian press release -- via Gematsu -- indicates that Siren may be coming back. In a since-deleted statement in the release, it's noted that Siren will be coming to PlayStation 4 alongside already-announced titles like Infamous: Second Son, The Order: 1886, Rime, Helldivers, Shadow of the Beast, and Everybody’s Gone to the Rapture.

However, Keiichiro Toyama – the director of each Siren game – noted on Twitter (via VG247) that he doesn’t know anything about the game, nor is he involved with it (if it exists at all). Toyama made his name directing and writing the original Silent Hill before creating the Siren franchise. He’s still with Project Siren, currently toiling away on the recently announced Gravity Rush 2.
The original Siren earned a 7.7 on IGN, with Blood Curse earning an 8.4.
If Siren is indeed returning, it’s indicative of the slip-up that accidentally revealed Gran Turismo 6. Long before Sony and Polyphony Digital were ready to reveal the game, SCEE senior VP Michael Denny spilled the beans. Could this be a similar situation? We’ve reached out multiple times to Sony for comment and will update if and when we hear back.
