VN designs are still very common in smaller CPUs (embedded stuff).
Even modern desktop CPUs are "logically" still Von Neumann designs
from the programmer's point of view (there's only a single address
space for both data and instructions). The fact that there are two
sparate caches is almost entirely hidden from the user. If you start
to do stuff like write self-modifying code, then _may_ start having to
worry about cache coherency.
