Yes. For the 7600 platform that is the case. There will be a new SXH train
called Whitney that will be focued on the 6500 platform. Basically the 7600 and
6500 are splitting.

If you want to prepare for what will be coming down the road you need to
go with SRB. A lot of customers are parked on 12.2(18)SXF because it is still
being rebuilt. The only reason it's being rebuilt still is because of some
hardware support that isn't in later releases (ie: sup2 I think it is).
