I don't recall any codes coming out before November of last year for this January and February. Also keep in mind, things are picking up at the WDW resorts.
Codes will probably be available but they may be few and far between and resorts may be sold out if you wait for the codes. If you have your heart set on one specific resort you might want to book it now and then try to get the code when/if it's available.
I recall during the "busier" years even when special rates were available some resorts would sell out of the rate or not even offer it there (this happened at WL a lot). Just something to think about.
