I beat the main storyline a week ago and went the Yes Man path. When you beat the game with this path he says to you " I found some code snippets in one of Mr. House's databanks that will let me um, reprogram my personality! To be a little more assertive, basically! "

If a DLC does come out and we can continue the game, I fear that when Yes Man does this, he will be stronger and not take orders from the courier. Thoughts?

thats what I thought to.

i don't think a DLC like that will ever come out, because of all the different paths the courier can take. they would have to create the new content for all the factions. with the Legion path, the Legion completely took over the Mojave, same with NCR and House.

Not saying it's probable, but it would be bad ass if they did do a DLC like that.

Even so, I think that with this path one could assume that Yes Man will become just another dictator and not listen to the Courier.
