Yeah, the Pro and MMX were totally different market segments, not alternatives for each other. The Pro's competition at the time was DEC Alpha, PA RISC, etc. It wasn't a chip that made sense for ordinary PC users at the time.
Later, when Pentium MMX was eventually replaced by Pentium 2 for consumers, the successor of Pentium Pro was the first Intel Xeon CPU (which was a slightly enhanced Pentium 2, with bigger cache memory and with ECC memory).
The launch of Pentium Pro in 1995 was the moment when Intel segmented their CPU line into CPUs for consumers & server/workstation CPUs.
