Same like Sup-2T new RSP-2T could do it. Wondering if new Sup-2T will
be MIPS or PPC. Probably PPC and IOS XE same like Sup7 for 4500. This
means Sup-2T can be the same for both - 6500 and 7600 series with
exception regarding IOS features - SR release (7600) versus SX release
(6500).

In fact currently all 7600-S series chassis can provide 80Gbps per
slot. From 6500-E chassis only 6509-V-E supports 80Gbps per slot. So
7600 is more capable of 40Gbps for linerate 8x10GE cards for near
future.

Like always Cisco can do oversubscribed 1:2 like WS-X6708-10GE :-)
Don't forget about local-switching at DFC... We have 7603-S deployed
where nearly all traffic (90%) is local switched at 8x10GE card. So
oversubscription here is not big deal.

But if you already got a lot od 7600-S chassis and ES/ES+ cards then
... it's like 7600 will dropped to lower capacities PE router.
