Correct, NetFlow is generated when the packet enters the router.  
you'll need Engine 3 or 4 cards on your ingress ports (GigE I assume 
for outbound traffic) in order to do line rate with full Netflow.  
Engine 0 & 1 cards can do sampled netflow which *may* be enough for 
your load balancing needs.
