I really, really, really hope you're right.
I'm kidding! I've probably played an Intelligent Systems game, even (Just not Fire Emblem)! Did they do Advance Wars? That sounds right.
Anyway, I'm not a fan of their musicians or artists (I'm not not a fan, mind), whereas I'm a huge fan of MegaTen art and music. The reason I'm so hyped is because in my mind at the moment, it's a game created by these developers that I love. If they aren't involved, then my interest drops to near zero.
I was joking as well, yeah they did advance wars. That said maybe they'll have a mixture of tunes to please both. I'm more than sure the gameplay is what they are working with Intelligent Systems for. The Megaten team should be in charge of everything else. I guess think atlus with arc systems works with p4 arena where arc did the combat system,menu,etc and atlus did the story,music and art.
