I know this is very very unlikely but I've just thought, What about Quakecon? I'm sure Quake was done by Bethesda, So maybe just maybe they could reveal Bethesda characters like Dovahkin (Skyrim), The Lone Wanderer (Fallout 3) or maybe even Doom Guy. I think if they did include a Bethesda Character it could be Doom Guy as first DOOM Game was on PS1 and DOOM 3: BFG Edition is coming out on PS3 a few weeks before All Stars. Like I said it is very unlikely but weirder things have happened.
Sackboy Ratchet and Clank are my 1and 2 that need to be revealed followed by..
Sir Dan and Spike
Nathan Hale (or Resistance Rep) and Nariko
I like the New Challenger Videos showcaseing all you need to know about the new comers..hopefully we get another one or 2 sooner rather then later but 4 characters a month is something i enjoy Jak and Daxter and Cole is Amazing!
There hasn't been one characters reveal through that, not even a stage, item or game mechanic information.
Why would they start now?
If there was going to be someone from bethesda I think it would be Ruby from the game "Wet"
What is with you wanting females from shi**y games haha?
