There is some datamining revealing some interesting Origin companions, but a lot of that is speculation based on incomplete pieces of code and writing.
Yeah, that's always a bit hazardous; and experience from released games is that you find loads of unused content when sifting through the assets so it's impossible to say how much of what's been found will end up the same, or changed or deleted altogether. It's an interesting exercise but I think it's too easy to make assumptions that it's somehow definitive... btdt etc.
