Famitsu (via Siliconera spoke to Sega-Sammy boss (as well as Index Corporation president) Naoya Tsurumi about the recently finalised acquisition of Index Corporation (owners of Atlus) and the subject of letting Atlus work on dormant Sega IPs came up:
"Famitsu: It must be reassuring to have added a group capable of making great RPG titles.
Tsurumi: While we have no intention of forcing this, we'd definitely love to have them utilize any of Sega's dormant IPs.
"Famitsu: Sakura Wars, Jet Set Radio, and Space Channel 5... are some that come to mind.
Tsurumi: There are plenty that haven't been active. [laughs] However, the new company just recently got started, so there's nothing on the table for now, but we'll definitely be giving it more thought."
