Disney Store will not; however, most Supermarkets, Costco, Ares Travel, Undercover Tourist will most likely have the lower prices. Also, City Pass prices do not go up until the 1st of the year.
With City Pass, you get a 3day park hopper and one day at Universal Studios (unless you buy at Universal and use it there first, then you usually get two days at Universal, but check this first) and a day at Sea World for an extra $59 over the current admission price. Seems like a pretty good deal.
Ares travel does have discounts off the old ticket prices, for a "limited time" and given the price increase, I would say it will be a very limited time. You can also get an additional discount, if you subscribe to the Mousesavers newsletter.
