BioWare - Mass Effect 4 - What we know

Eurogamer brings us news about what we know about Mass Effect 4 so far:

The story will focus on a fresh protagonist who won't be another version of Commander Shepard, BioWare has said, but while there will be no direct continuation of the Commander's story, nods to past adventures will be included.

Here's a little more information abouy two new alien races in ME4:

The attendee had claimed that the two new alien types they were shown included an "arrogant", skeletal race with glowing eyes and an "ancient, advanced guardian" race with a sci-fi golem-like look. Mako-esque land vehicles were also apparently shown, with different models for various environments.

It seems that ME4 will be Bioware's main focus in 2015, according to a post written by Chris Priestly, Bioware's former community manager, in the official forums:

Then, after the success of DA:I and at least 1 major DLC, we'll learn about MENext at E3 2015 and the focus for BioWare will shift from DA:I to MENext for 2015. Then MNext becomes the focus for 2015, launching in 2016 (or maybe late 2015 dependng how Montreal ramps up as a studio). Then things repeat as above in 2016 as Casey reveals the new IP his team is working on, then in 2017 DANext.
