Count me among the Delsin admirers.
I'm assuming four powers and switching between power sets with the d-pad, but nothing official has been said so far.
It's been pointed out before, but some of the trailers have made it look like stone powers will feature in the game. This seems likely, both because it would replace the highly adored ice jump from I2 and because rock fists make for fun melee weapons.
Neon, since we now know it's officially a power set, could be used in all sorts of stealth applications. Turn out the enemy lights. Throw up some distractions, or make electronic displays go crazy. Mitigate sniper threat by depriving them of a laser sight. I doubt Sucker Punch will do us wrong, but this is something I would love to see.
If we did end up seeing water powers, I'd love for them to be of a darker inflection, similar to blood bending from the Avatar series, and verging on psychokinesis. See a tree or crop of vines that would make good minions? Flood them with your unholy water. See a person who just won't get out of your way? Manipulate the very blood in his body.
Sucker Punch, you want interesting moral decisions? How about making players decide if there's ever an appropriate time to force someone to do something not of their own volition? How about getting to use the powers for more than limiting who I kill?
One of the most interesting choices the InFamous games have given so far, in my opinion, is from I1 when you had to choose whether to make the civilian open up the tar valves. You don't really see the effect when you do the selfish thing, but getting the tar on yourself sucked for the next short while, making it something of an actual sacrifice.
