HALO 3 on XBOX 360?

I though there are some rumours that HALO3 could be release on XBOX 360 but there has been no evidence. My friends told me that HALO3 could have a newer and a better engine than Halo2 which could almost be as similar to HALF LIFE 2 engine. I should check on IGN for more updates . I can't wait to play that game. Hopefully it isn't on XBOX 360. Oh feel free to post any comments if you like.

Hey the XBOX 360 looks cool on the internet
and in the pictures. I do hope it keep up to it's
promise and standards.
