A mysterious visitor in our forum, MoBill, dropped a note in our forum about an E3 Preview at Daily Radar. It includes the following information on Halo:

Halo -- Sure, it was the big game of last year's E3 (along with Oni, which is fast approaching whatever happened to? status), but we're still wowed by Bungie's technical demos of Halo. This year, the company is promising to show us some actual gameplay, along with another secret new game. The engine is definitely there -- will the gameplay live up to it? Cross your fingers.

I'll tell you that c can't wait to be there! We'll let you know as things develop.
