Yes, in higher densities.  See URL for info.

" The Cisco 7200 VXR systems include a 1-Gbps midplane and up to six
high-speed adapters configurable in a Cisco 7200 router when used with the
new NPE-300. The VXR series can use the NPE-300 (Network Process Engine)
which is the highest-performance processor in the VXR series (not available
in the 7204).  NPE-300 performs at approximately 300,000 packets per second
(pps) in CEF switching, a 50 percent increase over the NPE-200 processor's
performance.  The NPE-300 uses a high-performance 263-MHz RM7000 RISC
processor and can support up to 256 MB of memory providing superior
performance for both enterprise and service-provider applications that
require processor-intensive services. Network layer services such as traffic
management, security, and QoS benefit significantly from the high
performance of NPE-300.  In addition, the VXR midplane includes a
Multiservice Interchange (MIX) that supports switching of DS0 time slots via
MIX interconnects across the midplane to each port adapter slot. The
midplane and the MIX also support distribution of clocking between
channelized interfaces on the Cisco 7200
VXR to support voice and other constant-bit-rate applications"
