"Mass Effect: Andromeda" has no official date of release and all the original Trilogy Species are not included in Adromeda. However, they are presumed to be included on other Mass Effect games.
Mac Walter is the creative director of Mass Effect. He stated that they designed an IP that could allow users to show all the trilogy species according to Gamespot. Unfortunately, they cannot be available on the first game.
But the creative director assures that players will still meet all the original trilogy species in the near future. The Tempest will also accompany the players on their ships and there are some species added that were not seen in the previous series.
The developer of "Mass Effect: Andromeda" is Bioware and it said that Andromeda is the biggest game ever. The fans could also expect some more Andromeda games along the way. However, it pointed out that having a trilogy has no significance.
On one hand, EA is the publisher of the game. In the upcoming Game Awards on Dec. 1, 2016, the publisher will disclose other gameplay for Andromeda. The developer Bioware said that species in the original Mass Effect Trilogy seen by players will not be included in "Mass Effect: Andromeda" according to IGN.
