Yeah, at the very end there it was almost like they were building up to a huge reveal but then nothing really. I think it might have made more of an impact if we knew exactly what they were hoping to find, and not simply "earth"...

Obviously that can't be the end of the story cuz we still have 10 episodes to go. I read somewhere that there will be another series of webisodes between this half of the season and the latter.

I think there are also plans for a few more 'Razor' type films set ater the conclusion of the series so I'm really not sure how the end of the season is going to play out.
