I agree, but something must be added.
A pure IPS can't replace a firewall if it's doing just application 
protocol analisys/control. You still need policies. A IPS-firewall 
(stateful inspection + policy + layer7 inspection) can replace and 
sometimes do better than a firewall (stateful inspection + policy)
