Some new products are being delayed but others are just too important - or too far along - to hold off on.

With the economy crumbling and sales way down, GM announced some drastic steps Friday. Among them were delays in the carmaker's product development plans.

In the auto industry, that's a scary move. Delaying new product means delaying the increased sales that come with them. Not all product programs were put off, however. Some are simply too far along to bother delaying. The investments have been made and it's time to reap some of the benefits.
