They're pretty cheap even before the Christmas this year, because of the way things are, so i'd say it would look good for them to fall in price in January again. If your not in a rush for it then hold on and see.
Normally console prices are fixed by manufactures, the only deals you get tend to be with bundles. None of the manufactures tend to lower prices straight after christmas they typically wait a few months - thats if they lower them at all. The other main time the lower prices is before they release a new console to replace the existing one.
