The Trailer
Some stuff from reddit which a user got from the paid edition of the digital article.
No more light levels. Progression has been reworked so XP from kills, bounties, and missions will take you from level 1 to level 40. Armor, and now weapons, still have light on them, but it's not clear what its function is. Whatever it is, it isn't for leveling up your character
Pledge allegiance to a faction - no more class items. Trade in motes, weapon parts, armor materials, ammo synths, and planet materials for rep
Vanguard and Crucible marks have (finally!) been consolidated into one currency: Legendary Marks
A transmogrification-like system is currently still in the works: apply the stats of one armor piece to another armor piece you prefer the look of
Exotic version of The Strangers Rifle, called No Time To Explain; does Arc damage
"Energy types" can be applied to weapons. Not sure what exactly that means yet.
At least a dozen new exotics weapons - most of which are acquired by quest lines - and at least half dozen new exotic armor pieces
per class
Arms Day. Once a week, pay glimmer to Banshee to order a lot legendary weapon; weapon delivered to you on Wednesday
Banshee has reputation now. Level up and earn the right to test drive prototype weapons by performing a set task for each weapon (e.g. kill Hive; sniper headshots in crucible)
Shader and Emblem terminals! No longer take up space in vault. Access terminal to see every shader/emblem in the game, withdraw the ones you've collected so far, and - best part - see instructions on how to find any you haven't found yet
Guided exploration of the Dreadnaught. Strange items can be found and used for various purposes, like triggering a world boss, or discovering new loot hidden somewhere
When out in the wild, listen for audio cues to use your Ghost to scan the area for some object. Scan said object, and Ghost will talk to you about it and explain the lore behind it. This must be a way of building the grimoire in to the game itself.
Every piece of gear has perks, including GHOST SHELLS
Int, Disc, and Str now longer show a percentage on your character screen. Instead, it now tells you the time it will take for each ability to charge depending on the armor stats you have equipped
Emotes equippable below your emblem slot.
Helmet on or off now and extends to character screen
Cryptarch has quests
Active quest markers can be toggled on HUD
Old story missions have been rearranged to create a better narrative. Sword of Crota mission now flows in to The Dark Below storyline
You can hold more bounties, and turn in bounties without having to visit the tower/Reef. No details yet on how exactly you will do that.
Hadronic Essence, Plasteel Plating, and Sapphire Wire are gone. A single Armor Materials item now works for all three classes.
Crucible now adds to the story. Shaxx will appear to explain the lore behind certain aspects of it. New Crucible bounties each week. Complete all 5 of the new Weekly bounties for chance of legendary or exotic gear. New class specific bounties. Also, crucible bounties have been made less grindy and easier to complete. New fireteam bounties that encourage team play. Each day does have one particularly challenging bounty, similar to Iron Banner bounties. Trials of Osiris now has bounties too.
Crucible matchmaking has been fixed to match you with more evenly skilled players.
Marcy Rule in crucible will end the game if one team is getting severely crushed
8 story missions, but that is just the "first act." The raid is tied in to the story, and a bunch of quests are as well.
The Taken War is second act of the story. Revisit the Vault of Glass for part of this story arc, where we finally get answers about the faste of Praedyth
Four new strikes, one with two Cabal bosses at the end - a melee boss, and a boss with a mortar on his back. Raid-light mechanics are now part of strikes, encouraging teamwork and puzzle solving
Encounters in strikes can change on each play through. Confront different enemie races, or multiple races duking it out, at certain sections than you did the last time you played it. Taken enemies can be injected in to the strike at any point.
Exotic weapons have been reworked so the exotic perk is the first to be unlocked.
