I thought I had read that too on various DI wiki sites and such. They were supposed to come with exclusive power discs like the Frozen pack. But I can't find any official confirmation from Disney so for now take it with a grain of salt as they say.
Come on Disney, I know you want to announce Darkwing Duck next...
I know that I saw a pic of the box for 'Wreck-it' with Ralph, and Vanellope with two Hex discs, but not sure where I saw it. Also it does appear that the Figures will be singles as well.

We all have sparks. Imaginations. That's how our minds create creations. So they can make our wildest dreams come true. Those little sparks in me and you.
I believe I saw the box picture as well, but I looked on Google just now, and I could not find it anywhere.
But I can tell you that, at different points during the month of July, both Amazon.com UK and Amazon.com France had the following list up:
Releasing 10th December 2013 Rapunzel Girls 3 Pack Vanellope Wreck it Ralph Wreck it Ralph Toybox set
We also know that the French website "Micromania" had a listing up for a "Disney Infinity Worlds Of Ralph" box set. The confirmation for that is here
Granted, it's not official confirmation from Disney. It would surprise me if it didn't actually come out, though -- we've already seen video confirmation that a "Wreck It Ralph" skyscape exists (this is not the Sugar Rush skyscape, but an actual skyscape for Wreck It Ralph proper which shows the arcade title screen hanging in the air off in the distance).
That video confirmation is here:
Jump directly to the 0:08 mark. You can CLEARLY see the "Wreck It Ralph" arcade title screen hanging in the sky, and it's visible again at the 0:15 mark.
So we kind of already know what would be in the box -- the Ralph figure, the Vanellope figure, and the Wreck-It Ralph skyscape and land scape discs.
