On the eve of the Tokyo Game Show, rumors started to float around that Sega (the video game company that brought you Sonic the Hedgehog) was the winning bidder for the financially troubled Index Corporation, parent company of Atlus (videogame company known for localizing "niche" Japanese games in the West). After an initial denial, Sega Sammy Holdings did confirm that they were acquiring Index.
Sega will create a subsidiary named Sega Dream Corporation to take over the operations of Index. Cited specifically in the document the Atlus properties "Megami Tensei", "Persona", and "Etrian Odyssey". Sega plans to "exploit" some of these properties and expand them into the PC online games and smart device arenas and also for their Japanese "pachislot" (pachinko slot machine) business. The due date for the transfer is November 1, 2013.
The purchase is thought to be $14 billion yen (roughly $141 million USD).
No word on how this will affect the Atlus/Nintendo crossover title Shin Megami Tensei X Fire Emblem yet.
