The new "abilities" are persistent rather than one-time use like equipment. You'll use them like you use grenades. Only 2 shown were active camo and dash, but expect more.
Halo theme is not in.
This is not Halo 4.
Cut scenes use a handheld camera style.
New grunt currently nicknamed 'keg grunt'
The engine has been 'gutted' and just about every aspect overhauled.
Voice actors faces will be mo-caped.

Night vision as seen in ODST is in.
Motion tracker shows elevation.
