I’m not sure if this was mentioned or not, but on the bottom of the Summon Night press release Namco Bandai is mentioned as the copyright holder instead of Banpresto.
It reads, “(C) FLIGHT-PLAN SUMMON NIGHT (R) TWIN AGE &(C) 2007 NAMCO BANDAI Games Inc. Published and distributed by Atlus USA.”
This shouldn’t be a surprise because Banpresto was supposed to be fully absorbed into Namco Bandai by April 1, 2008. The upside is Atlus still has a good relationship with the folks working at Banpresto/Namco Bandai. And as long as the two publishers are working together there is hope for localizations of the Summon Night DS games, Super Robot Taisen: Original Generations and Draglade 2.
