Stargate Atlantis: Season Two

The following are my wild speculations about things that will occur during the second season of Stargate Atlantis. As long as you've seen everything up until the season finale, there shouldn't be any spoilers:

• We'll find out much more about the creation of the Wraith. The team has speculated, but their guesses don't feel right. In particular, how much were the Ancients involved, and was it really an accident?
• Why did the Ancients have a nanite virus lying around that kills humans but leaves Ancients alone?
• Are the Wraith only able to feed on humans (and no other species)? If so, is this a nod to their origins?
• It's been hinted at, but to what extent exactly are the Wraith able to read the minds of their victims while they feed? Did they all wake up en masse because they'd found out about Earth?
• Do the Wraith have a hive mind? How do they breed?
• We know the Atlantis stargate wouldn't do the Wraith much good; it's hardly a practical way of transporting their entire population. So if they got their hands on the city itself, or otherwise determined the location of Earth, how long would it take them to get there? How would Earth's defenses stand up?
• To produce their seemingly endless supply of ships, the Wraith must have factory worlds, a la the Death Star; we might get to see these bases.
• If the team is able to get their hands on a fully-charged ZPM, not only will the shield be up, but we might just get to see the city fly.
• And here's the most outlandish one of all: remember the episode with the spider-like cousin of the Wraith? Remember how it didn't much like salt water? Well, maybe the Ancients submerged their city for a particular reason. What a world, what a world...

For the record, I cheated a bit and watched the season finale already. It rocks. Don't miss.
