The Sup2T works on the 7600 platform with compatible line cards.
The ES+ is reported to be planned for compatibility with Sup2T.
No word yet if it is a part swap or line card swap.

I don't think it would make a lot of sense, and I don't think we'll ever see 
one.

If they rebrand the Sup2T as RSP2T, they would have close to no supported line 
cards (only 67xx without DFCs) and, specifically, all of the high-functionality 
line cards (ES+) wouldn't be supported. Yes, they could support 68xx and 69xx 
and spin new ES cards (ES++), but that would be fairly expensive. And for what 
purpose?

If you have a 7600 and you need to replace everything but the chassis and PSUs 
to upgrade to higher speeds, does it make sense to do so, when there's already 
the ASR 9000 available? A much better router at presumably approx.
the same production cost as a 7600 full of ES+. In my opinion, no.

What they *could* easily do is support the 7600 chassis in the Catalyst 6500 
software 15.0 SY. That I think they might, and there's kind of a poetic justice 
in it if they do, because everything would then be back to square one. Maybe, 
just because of that, they won't: It would look like they made a mistake when 
they split the two products ;-) (Hi Gert!)
