It's like 2008 all over again, but worse.  In 2008, the Sup2 was nearing 
the end of its ability to hold full v4 routes.  The "good news" back then 
was that you could upgrade to Sup720-3bxls for a little more than (IIRC) 
about $10k per unit.  This time, at least as of today, Cisco hasn't 
provided an upgrade path that'll keep the 6500 family usable for a 
full-table router when the "1 Million" route slots aren't enough to hold 
your 768k v4 routes and 128k v6 routes.

At this rate, if they do produce a PFC that takes the 6500 to several 
million routes, it's probably going to be too late for those to be 
available in any real quantity on the secondary market.  Maybe that's the 
plan.
