Heres a link from IGN that breaks down and pause rewinds the ME3 E3 trailer and explains loads of cool stuff.
Shame the two guys doing the breakdown know little to nothing about ME. I usually like hearing what what Arthur Gies (RebelFM) has to say, but hear he comes across so uninformed.
I agree, it didn't seem like they knew much about what they were talking about. "The reapers are using lasers like the geth." um.... no they are using lasers like reapers... Like sovereign had in ME1. derp
I think my little sister knows more about ME then those 2 lol
