Prometheus 3 Minute Long Trailer & Speculations

I've been keeping up with movie since the first trailer was released & during all that time I've developed a few theories about the film. These aren't spoilers & this trailer does relieve some SPOILERS! The following are personal opinions:  

1. This film doesn't even take place on LV-426. 
2. There are two different locations in the trailers & we have no idea what the other location is.
3. There's another group of aliens besides the Space Jockey's we get to see 
4. The atmosphere of the planet is very nice compared to the planetoid we see in Alien & Aliens. The weather is beautiful & surreal. 
5. That's a totally different Space Jockey craft then we see in Alien. That's right its a totality different craft carrying a completely different cargo may with some of those eggs. 
6. This is going to be another "57 miles of bad road" as James Camron described of his movie Aliens & is going to leave you breathless. 
7. There's going to need to be a follow up to this film & perhaps an expansion of the Weyland Corporation. This movie has had one of the most successful viral, advertising, over all coverage so far for science fiction film since Avatar. The advertising has single backhandedly restarted the Alien franchise. No more bad Alien movies please & do something more with Predator while your at it..  
8. Each & every little piece of this movie's viral advertising makes me want to play a campaign set in something like this universe. 
9. What is the agenda behind the Weyland corporation? Why were the colony on LV-426, this expedition, & the crew of the tanker expendable? Whose behind this & what technology or advantage to the human race is gained by the loss of life, money, investment, etc. What makes such a loss acceptable? 
10. The androids in all of the movies all have hidden agendas but again for whom? Ash, Bishop, & now David's concern is the science of the Alien species, the technology of the space jockeys, etc. 

To be completely honest with you this trailer gives away nothing & leaves you with more questions..
