This new commercial video shows off some new stuff as well.

In particular it shows how you can trade quests with other players via StreetPass (starts at the 4:20 mark). The quests include the target monster, stage and weapon apparently.

New Info on the Guild Quests, Expeditions and Unknown Forest!
Unearthed Gear
Up until now you were able to find Charms that were unearthed. Each was random and had different stats and abilities. They are now adding actual armor and weapons to that system. One neat new thing is that each new gear you unearth (by mining, rewards, etc.) will look slightly different. For example, they showed Rathalos armor that looked slightly different). You can find the same piece of armor or weapon, but with slightly different appearances, stats (like higher attack, an additional slot, higher rarity, etc.). The rarity works like charms, there stuff like rusted or weathered armor, etc.
Guild Quests
The most efficient way to find the best materials and items in the Unknown Forest is through Guild Quests. These are not quests that just exist like normal quests. When you go into the forest and hunt the monsters that are in there and mine the items that can be found, you receive a rating based on your efforts. When you leave the forest, if your rating was high enough, you can save that excursion as a quest, forever locking in the items/monsters/etc. that were there that specific time. You can then replay that quest, or share it with other players (friends, or though streetpass).
For the excursions you save as quests you can play them either single player or even with friends. As you clear Guild Quests the level of difficulty/rarity of the things you might encounter goes up. Higher level Guild Quests means a better chance to meet stronger monsters, and get better items. A Guild Quest lists info like if there is a ‘treasure area’, poogies, and what the tendency is for what kind of items you might find/get (lists both tendency for weapon and armor).
Unknown Forest
Like MH3U, there is an area you can go to anytime to do free hunting. This time it’s the Unknown Forest. It can be accessed via the world map.
The area is slightly randomly generated, so the actual maps, monsters, items, etc. will be different every time. Before you enter the forest you can see the details of the Forest (like MH3U). The details include if the area is stable, what large monsters are there, if there is a treasure mining area, if any wild Felynes (or Pugi? I think i saw on one screenshot) exist, and what kind of weapons/armor you might find (more in that below).
After you choose to go into the Unknown Forest, if you do enough (assuming this means you killed the large monster instead of just leaving), the Guild will save that excursion and the state of the Unknown Forest as a official Guild Quest. You can redo the quest as much as you like, this time solo or online, and even share it with other players. The idea is that no two Guild Quests are the same.
As you hunt in the Unknown Forest you will earn points. Earn enough and your Quest Level will increase. The higher your quest level, the higher chance that a ‘rare’ or high level quest in the Unknown Forest will become available. You’ll want to check what’s in the Forest between each quest I think so you don’t miss the opportunity to do a rare quest that might appear.
When you receive a quest from another player, it will drop to a certain level, meaning if you get a quest that has a very high rate of getting a rare item, the odds will be higher for you than other players you share the map with. A good idea to ensure balance is maintained in my opinion.
