Bungie only had access to about half of the gamer market during Halo. After leaving MS they needed to start planning how to approach the Sony side I'm sure. This is something they have to do because when you become free and have this access to basically all gamers (Wii aside) you kinda have the opportunity to sell more games. If they are as successful as Halo. Look Bungie loves Xbox. Bungie loves Halo. Bungie loves the Halo nation. However, it's time to move forward and for them to market to everybody. I think all the PS love is that they are excited to finally work on a console they have access to. I don't know. Just some of my thoughts on it.
