Incentives, sure... but the dealers will undoubtedly try and tack on this and that to get back to what they need want to be, to make to make a good (some would say reasonable?) profit on these vehicles for sale.
I doubt they would be so desperate this soon as to take anything approaching a loss, especially with any 2014's considering the 15's have still not even been "officially" announced yet.
As I have alluded on other threads, a lot of the "excess inventory" stuff is an illusion. It's someone else's inventory not necessarily the one doing all the hype selling. Hype costs zero. Deals undone cost zero. Holding inventory costs something, but we are not privy to who does or does not actually hold inventory.
The 2013's in someone's inventory should be available for very good prices. With good reason. When Yammi came out with the 2014ES for just 1k over the A model, with all of its improvements, and features. they really killed the 2013 value. THis is what happens when you do not control the marketing group well.
