A listing for Demon's Souls 2 on PlayStation 4 has appeared on the website of European retailer CDON.se.
The unannounced game was spotted on the retailer's website this morning. CDON previously outed Gran Turismo 6 for release on PS3 weeks prior to the game's official announcement.
The listing follows comments from SCE Worldwide Studios president Shuhei Yoshida, who told Polygon during E3 that he would "really like to see more" Demon's Souls.
"That's a great question, but because of the attention that will get, I choose not to answer," he replied, when asked whether Sony was interested in developing a sequel. "But personally, I love Demon's Souls. I spent hours and hours and hours [playing it]."
"I love the team, I love the game and yeah, I'd really like to see more. But that's all that I will say."
SCEJ published Demon's Souls in Japan in early 2009, with the European publishing rights picked up by Namco Bandai a year later.
Namco later went on to release spiritual successor Dark Souls, with a sequel due to release on Xbox 360, PlayStation 3 and PC next March.
While it's certainly possible Demon's Souls 2 could be headed to PS4, CDON also lists Microsoft-exclusive Dead Rising 3 for release on Sony's console. Yoshida's comments give us hope, but it's best to take this with a pinch of salt until confirmed.
