The VAX succeeded the PDP, though the PDP was kept in production for many years of overlap. They're different generation of technology filling the same niche. The PDP-11/70 was the beast of it's day, and even came in a multi-processor version (the 11/74). Saying the PDP was a mini and the VAX was a supermini is like saying the 286 was a mini but the 386 was a supermini.
