http://www.gamasutra.com/blogs/ChristianNutt/20130920/200739/Whats_going_to_happen_to_Atlus_postSega.php This has to be the most factually grounded, objective and nonpartial shakedown of the situation so far.
Oh boy, I'd love this. Jack Frosts are just awesome. I really hope for Sega to let Atlus continue their operations as they did, even though trying to get more profits.
http://sega.jp/corp/release/2013/1101/ it appears Index Corporation is now called "Sega Dream" (at least that's what einstein95 from tcrf is claiming this says)
Details via Siliconera via Famitsu. Siliconera's headline (Atlus free to use dormant Sega IP) is probably the most welp of this. Spoiler: Atlus won't be going away any time soon.
