Well. Not sure if it's a leak, but you can't actually add them to your cart... but Toys R Us has posted up listings for various new items to pre-order:
(Item Name - Price - Listed Ship Date)
Wreck-It Ralph Toy Box Pack - $30.99 - 12/10/2013
Wreck-It Ralph Figure - $13.99 - 12/10/2013
Vanellope Figure - $13.99 - 12/10/2013

Girl Power 3-Pack - $30.99 - 12/10/2013
Power Disc Series 2 - $5.99 - 11/19/2013
I mentioned in another thread that Toys R Us also posted up their exclusive power discs packs the other night before taking them off, but I thought I might as well restate it here. The packs were $4.99, had gold packaging and a "Toys R Us Exclusive" type labeling. They were being limited to 5 packs per customer. This means that you shouldn't pre-order a normal pack from Toys R Us expecting to have a chance at the exclusive 10 discs.

Toys R Us has posted the Toy Story Playset for pre-order. $35.99, release date is 10/15/2013. Not picture or description of included figures.
I wouldn't say this listing was accidentally posted early, since most test listings on Toys R Us don't allow the order to actually be added to the cart.
