NaviBlast is being featured at
DemoCamp here shortly; it'll have a venue of about 180 people, most of which are execs in the gaming industry. Tonight will be the first public showing of the game deployed on the Xbox 360.
After DemoCamp, there will be a sit-down dinner between Stephen (programmer), MJ (pseudo-publisher; financial backer. Former employee of Cambrian House, current member of Broken Kings), and the Microsoft Evangelist (who's name eludes me. I'll tell you all when I hear back from Stephen), and they will be going over release details for the Xbox 360.
If all goes well, we could see a release of NaviBlast for the Xbox 360 soon!
