The unfortunate thing for Toyota is that things could (potentially) get worse for them ...
When you combine the higher MSRP, lower incentives, and higher interest rates associated with (many) Japaneese cars they have been noticeably more expensive than their American counterpart for quite some time. Over the past several years people have justified this higher price because of their superior fuel economy and their better resale value; and their resale value was often inflated by used car buyers willingness to pay a premium to own a more fuel efficient car.
If oil prices remain at more modest levels, and people are more careful with how much money they are spending on a new/used car a company like Toyota may be more negatively impacted than other manufacturers.
