Has anyone entertained the idea that the probable protagonist shown in the trailer goes through a moral progression and serious change throughout the game? I doubt the developers would step away from the duality of the moral choice system when that was partially why the original games were titled "Infamous" in the first place, especially when it is a cheap way to get two play throughs. But think about it, his fire/smoke powers are red, which always implies "bad" in video games. But as fire gets hotter, it turns blue, which is an implied "good" color. So I'm guessing they will tie that in with the story. Possibly, as you get stronger you may have the choice to go good, or stay an angsty dick.
Just for the record I love Infamous, I platinumed both and even though I think this is a TERRIBLE trailer, I'd be lying if I said I didn't want another Infamous. But as much as I love Cole, a direct sequel with him as the protagonist just doesn't make sense because the ending of Infamous 2 is airtight. Now an Infamous prequel where you play as "Kessler" Cole before he goes back in time would be interesting, especially if you build up to the desperation only to meet your final demise at the hands of 20 something you, but it would be very much a stretch.
