Movie and Game to be called Forerunner?

There's (miss)information flying around that the next game in the Halo series will be called "Forerunner". This new game will be a detour from the linear, single-player based version. TotalVideoGames comments:

The story behind the title will allegedly focus on the origins of the
Forerunners, the mysterious race believed to be behind the Halos, suggesting
that the Master Chief's return to Earth will be delayed until the true Halo 3
begins. The thread continues to describe an experience in which failed
objectives do not mean the end of a mission, but instead a different set of
circumstances to face up to.

All we can do is wait and see.
