The rumours that I've seen floating around in public places (based on
easily googled cisco docs) indicate that the sup2t will be earl8 based,
will support 80G per slot and will have a new range of 80G line cards but
will also run 40G line cards (although it's not clear whether running mixed
40G/80g line cards will pull the entire chassis down to 40G), that it has
enough fib tcam for 1m ipv4 entries, that it will support 512k netflow
entries, and that it will be 65k only.  These are slightly older rumours,
so things may have changed recently.

I wouldn't be surprised to find out that it had a different software image,
just like the rsp720 does (ppc vs mips), but would be surprised if Cisco
kept it on its own software train.

I'm inclined to believe Cisco when they say that they will maintain the 65k
chassis for years to come.  It's a massive cash-cow for them, and one
doesn't throw away a money printing device like that just because it has
last year's colours on it.

On the other hand, it is disappointing that the sup2t has taken so long to
materialise.
