Since the other thread on in this section is out of date and the game is no longer what people were expecting, I will create this thread and keep it up to date as new information comes in.
Eternal Crusade is an upcoming Warhammer 40,000 MMO/shooter that is due for release at the end of 2015, it is said to be in the style of Planetside 2 but with more emphasis on the MMO part, most things are pure speculation at the moment and facts will be added as and when they are confirmed.
What business model will the game use?
Although it’s still under consideration, the current plan is that Eternal Crusade will be “premium with a free-to-play option.” By purchasing a copy of the game, you will have access to it forever with no need for a subscription. There will be post-launch expansions, as well as a cash shop for customization & convenience items. If you don’t want to buy the box, you can still try the game as a free-to-play version of an Ork character. As opposed to the premium Orks, your progression will be slower and some options will be locked off, but you’ll be able to go anywhere and fight for the Waaagh! If you like it but still don’t want to pay the full price, you can unlock some of the missing options with microtransactions.
Eternal Crusade is partially F2P. Without paying, players can access the game but are limited to Ork Boyz, who cannot advance beyond a certain degree. Those who buy the game have access to all factions and full advancement. There is no monthly subscription, however a cash shop is planned.
The game will be mostly PvP, happening on one planet at a time. A new planet will be rolled out when a planet is conquered. Tyranids are NPCs and will be used in part to keep things a little bit balanced if player faction numbers are too unequal or one faction is dominating for other reasons. They will also constitute the PvE content, probably all of it.

Tyranids
While Tyranids are confirmed to be in the game, they will not be playable. Instead, they will be an NPC faction, providing enemies for PvE content.
Eternal Crusade will also feature an EVE-like single server, though Caron pointed out that the game's economy is "a very simplified EVE."
Other mechanical tidbits include a three-pronged advancement hierarchy beginning with squads and moving on to strike forces and then war councils. Caron said that the councils will ultimately decide objectives for the game's players via their chosen faction, though he also noted that you don't have to follow the hierarchy and are free to strike out on your own. Hierarchy XP bonuses may dissuade you from doing so, however.
The game will also feature friendly-fire, though it will have some sort of "reduced potency." The concept is still being ironed out, but Caron explained that shooting a friend won't be exactly like shooting an enemy. If you're an experienced player in mechanical terms and you shoot a friendly, you'll get a harsher penalty because you should know better. If you're a low-level player and you shoot a friendly, you'll get some sort of debuff that says you're bad at shooting.
