Expected. Not really much else I was thinking was going to happen with all the project arkcon/Ark theories and whatnot. Not really much else that could happen unless Andromeda skipped the arrival to the new galaxy and placed us in a ME1 type situation again.
I think it's outstanding and fertile ground. You could play colonialism straight as humanity's hero (justified as 'we have no other choice'), or you could play it as 'humanity is the bad guy', with all the shades of grey in between. Either way, the focus will be on exploring alien planets and meeting new races, and all of that sounds like gravy to me.
