Good ideas for inFamous 3:
You choose the life of a randomly powered Conduit ( fire, water, air) operating on the West or Central America (so not conflicting with East Coast Cole).
Either 3 storylines:
1) After Cole's apparent wiping out of the Conduit gene all over the Earth, he seems to be the only one still alive. The plot is how he discover's his powers and him being hunted down by government and private organizations in an attempt to study his body and why he is the only Conduit left alive. He can either make the choices to to flee with sidekick while helping out plague infested cities across US or fight back and being the only Conduit left rule the world.
2) While Cole is undergoing the events of inFamous 2, you come across powerful conduit who is also adapting to life with recently activated powers in the Midwest Usa. Learning of the Demon of Empire City another person with similar powers , he travels across the Usa to meet with Cole, while fighting off NSA and Darpa as well as the First Sons to reach New Marais. He has some sort of encounter with Cole (maybe helps fight off the Beast at a suitable time to not conflict with inFamous 2 storyline) and helps in some streches of time to also being one of the peoples wiped out after Cole actiates RFI.
3) Time before Cole, when FirstSons are testing affects of Ray Sphere. Experimented on he escapes and flees across country to escape persecution.
Whatever it may be I just hope SuckerPunch come up with a good quality inFamous 3. Can't wait to get festival of blood
