Music (end-sequence) HALO4 - E3 2011

Hello,

on the E3 (2011) HALO 4 was first presented. In the end of the trailer an extremely awesome sound could be heard. I think it’s an modification of “Opening Suite”. I tried to find this sound but it’s nowhere to find. Maybe it’s only a short sequence specific for the E3 but I want to have it.

Does someone know where I can find it etc.?
best regards, R.K.
