IMO it would have been so much better and more epic if they got the real Chief voice actor in for the role.
It seems that the master chief shown in this video is most likely from the beginning of the Human/Cov war because MC is meant to inspire the guy which this series is based on to become leader of the UNSC Infinity many years down the track. Alsothe video contains people saying this is a whole new war hinting at the idea of an unheard of enemy. From this it is easy to deduce that master chief (being born in 2511 and the covenant war starting in 2525) would have been around the age of 20 (give or take a couple of years) during this video and it would be odd to have the voice of someone much older especially his voice from H1-3 where he is aged 41.
