Bungie, who left Halo development and moved on to multiplatform games, have hinted that they will be revealing something in the coming weeks. The game will be featured on both PS3 and 360, other details are unknown but that may soon change.
Bungie Weekly Update: 05/27/2011
““Yup, truth told we have been less and less active on Bungie.net as of late. Part of that is owed to my aforementioned travel arrangements, but a significant amount of my time is also now being dedicated to other upcoming endeavors that won’t make a splash on the front page until Bungie Day closes in around us. Unfortunately, that means there are just too many balls in the air for me to juggle without letting a few fall to the ground.
More explicit details about those balls in the weeks ahead.””
E3 is coming up so it is possible to see their multiplatform game, although they have already stated that they will not be attending E3 this year. The next possible date is Bungie day, which is July 7th of this year.
