I'm in love with Jesus and proud of it!
I looked on the screen and didn't see any icons for AA's like you see in Reach, so either they're gone, have been replaced, or Sprint is simply a default ability for everyone.
The thing about "perks" and "custom loadouts" sounds eerily like CoD. I hate the CoD perk concept (whoever plays the longest gets the best guns, armor, etc) and if this is true then Halo MM will be unplayable by long-term fans of the franchise.
If the gameplay is faster paced and more intense than Reach then fine be me, as long as it plays like Halo. But what I see is 343i trying to compete too hard with other shooters rather than trying to keep the good ol' classic Halo feel. It's a shame to see something as awesome as Halo become yet another carbon copy of CoD, and I hope that when the game is released, we'll be pleasantly surprised rather than disappointed by what 343i has done.
I'm still getting it. I'm a huge Halo fan and I won't pass up the next installment just because the MM is different. I don't want to use the "adapt" argument because that isn't fair, you shouldn't drastically change the feel of each successive installment. However, regardless of what they've done, I'll still love Halo.
