2 Series vs Value Line

I am comparing an MSP430 2 series part to a value line (g series) part and was just wondering why the cost difference.

If I have 2 parts that meet all of my criteria why is the g series part so much cheaper?

Is it because it is newer and cheaper for TI to manufacture or is there something else I am missing?

For example. MSP430F2132 vs MSP430G2453

Thanks

Engineering resources can be spent to either make new features or to reduce the cost of an existing product.  In the case of the MSP430 Value Line devices, the emphasis was on lowering the cost as compared to the 2 series equivalent.  As a result, some subtle differences exist between them and their 2 series equivalents (as noted in the discussion above).  If the customer is already using a 2 series part, there may be an engineering cost to migrate to a Value Line part.  However if it is a new design, and devices from either the Value Line or 2 series fit the requirements, I'd say go with a Value Line device.  As a general rule of thumb, I would check to see if a device would fit the requirements in this order: Value Line, 5 series, 2 series. . .
