Mrs Y is actually Yutani. She is the owner of one of the corporations that form Weyland/Yutani which is the mega-corporation that is in the Alien and Aliens movies.

While you do seem enthusiastic, I would definitely recommend reading the AVP books out there. They are pretty cool and will give you some good background information on both races. Even if you just read the Alien books.

Some Non-Spoiler info:
-Aliens do not have a 'homeworld' of their own. They are a bio-engineered weapon created by the specis you see in the first 'Alien' movie. The frozen corpse in the derelict spaceship that they find.
-There is no master Alien. There are only hive Queens. Their closest match are ants in terms of social structure and behavior.

The problem is that the crashed ship in 'Alien' was an entirely separate species. They were the ones who actually created the aliens as their own weapon. It would be very hard to bring them into the picture without compromising all the other storylines. I think that AVP should keep a separate story flow as the regular Alien series (if that ever comes back).
It would be cool if the third movie shows the birth of the Colonial Marines as a mercenary group taken on from Yutani (which turns into Weyland/Yutani) which is obviously a defense contractor for the US Military. This would keep the storyline intact with the regular Alien series as they did know about the Aliens from the get go and have been obsessively hunting them ever since. The reason I would like a Colonial Marine'esque unit to come into the picture is I don't know how many more times they can run the 'poor humans stuck in the middle' plot line. I would also like to see the girl from the first movie brought back to take on a Ripley type roll in the series and for her to go a little more hard a@@ from experience gained from the first one. Ripley was always a tough cookie but she still was a non-warrior. I think that they can safely turn the girl from the first movie into a true lead warrior and not make it seem forced. Without giving too much away from AVPR, I don't think the ones from this movie could take a star role in the next one. They could be good back-ups or second stringers but none of them really captured me as leaders.
What I would really like to see for the next movie would be a hive assault on a planet that has already been taken over by the aliens.
Hopefully this will spark interest in the main Alien storyline because I would love to see an Earth War trilogy.
