Hehe, did you watch my video

The third question, I think, has been heavily misinterpreted, though I can see why. What they apparently did was show a lineup of the
main races and asked members of the audience to pick and remove two
if they absolutely had to. It's like asking "what's your least favourite, which do you care about the least".
I firmly believe they asked this
not so they could whitewash Krogan, Quarian, or whoever else
from the entire game universe, but were instead prying to see which species would be
most viable for
player characters. I strongly suspect Mass Effect 4 will not just have a human protagonist, but also let you pick two or three other species, similar to the way Dragon Age: Inquisition is set up. In a perfect world every single major species would be playable, but this is
not viable taking into account the massive cost of time/money/testing on BioWare's end. So how do they work out which
major species (this is what they asked, not minor species) to focus on being playable, and which to focus on being secondary???
Simple: Ask the fans which two are the least favourite and which, if they had to, they'd remove. If an overwhelming majority say "Remove Krogan" that
does not necessarily mean Krogan are flushed from the entire game universe, story, secondary characters, side quests, major quests, or anything like that. But it does lower the priority of making Krogan
playable in the single player campaign, in favour of making other, more popular races optionally playable.
