It seems that the mods over on /r/MassEffect have just received a leak of information from a source saying they have access to an early version copy of the new Mass Effect game - Mass Effect Andromeda.
Although they did get proof of the person's identity the mods were asked not to share it publicly, so there is a chance that some of the information might not be real. On the other hand it could all be for real. We won't know until closer to the time.
Included in the information was new of the character you supposedly play as as well as the mission the game is centred around. There were also details about some gameplay elements, including the reveal of two companions who can join you during gameplay and the fact that you can take two members of your squad on missions with you as the others stay behind on the ship.
The ship itself is said to be larger than the Normandy and there was also details provided on how you get from place to place. The enemy forces were also touched upon, with them apparently being dropped off in Cerberus ships.
Planet surfaces will be explorable and the combat will be greatly enhanced with the user of jetpacks to allow you to get to vantage points up high or across larger gaps and the omnitool now having a function to be used as a shield.
If you're interested in reading more, or joining the discussion over on /r/MassEffect then navigate yourself to the thread over here.
Either way, we won't get to know how legitimate any of this information will be until BioWare start releasing more official information next year.
