Although... we've only seen environment discs for Sugar Rush so far, and we do know from the El Capitan presentation that there is a Fix-It Felix, Jr. environment in the game... so I'll remain hopefully optimistic that we'll still get a Wreck-It Ralph playset.
edited again with that new info. looks like we have the new category of weapons now also check out minion's link. the picture is awesome. at it looks like mounts and weapons are now orange instead of pink.
