Not 100% sure on this but the 12008 chassis is 2.5G per slot so you  
are limited to LCs that are 2.5G.  I think that is E0/1/2,  E3 is  
10Gig isn't it?   He could upgrade the chassis now to a 12410 and use  
the existing E0/1/2 line cards.  He could then upgrade the GRP to a  
PRP-2 and later upgrade the LCs as needed.  The point with the 12000  
series is you can do the upgrade incrementally.   The 12000 series is  
also distributed (dCEF) which will get you the capability of orders  
of magnitude more PPS than a single processor (CEF) based 7200 or 7300.

If you decide to junk the 12000s send them to me,  I'll pay freight :)
