I do not quite understand the security model underlying the CVV2. Isn't it the case that credit card numbers are typically obtained by making the user enter them on forged websites or by sniffing network traffic? Now what additional security do I gain if all such transactions will soon require to give the CVV2 as well? The same online methods used for stealing the credit card number can also be used to steal the CVV2.
