wow, theres a barrette 50 cal, and a m9 by the looks of it!!
Where in the world did you see that?
I think he's confusing whatever the Anti-Materiel rifle is and the Hi-power for a Barret and Beretta. (lol, similar names.)
At about 1:38, with a gas mask? Yeah, looks cool, but its just combat armor right? Makes me wonder how PA will be introduced into the game, if there's no Enclave or BOS. I'd say the eyebot represents the last of the Enclave on its way to NV, except that its playing the wrong music.
The A7 armor is an advanced form of combat armor, I'd say. That gas mask seems to have some sort of optics system built in too.
BOS is in fact in the game, just not a very large faction.
Enclave may or may not be in the game, even as a small faction it hasn't been confirmed either way. But the enclave themselves don't even have to be in the game for their power armor to be present. You could find an old enclave vault with armor sitting right in it, and I bet that the BOS have some Enclave armor stashed away somewhere.
