The only scheme I’ve seen thus far is this one…
RT = Fire
LT = Smart Scope/Stabilize?
LB = Throw Grenade
RB = Melee/Shoulder Charge
RS = Aim/Crouch/Ground Pound/Slide
LS = Move/Sprint
Y = Swap Weapons
X = Reload/Action Command
B = Thruster Pack
A = Jump/Clamber
D-Pad = Cycle Grenades
Back/Select (old reference) = Scoreboard
Start (old reference) = Pause Menu
… I assume it’s the default scheme and it looks like a pretty good one, but I’m still hoping that 343i will offer us button remapping capabilities to ensure that we’re able to fully customize the control scheme that works best for us (individually). If that’s unfortunately not the case then I’m hoping to at least see some schemes like these so I can try them out…

…as well as several additional variants based off of these.
