Yeah of course they did... every generation is going to be better than the one before it (unless you're intel for the past 6 years) - the 32C part from a year ago was $1800, the new part is $2k - that's price creep. Is it a massive change? no not really; hence 'creep' next gen if it's out in front will be a bit more, and then a bit more etc.
you can make the $/performance argument somewhat, but this is just history repeating itself... AMD took the lead with K10 back in the day and then slowly increased prices until:

until a year later intel came out with a $183 chip that would smash that $1k chip.
So yeah... I would stand by the price creep statement given how fast technology advances. I think zen offered people sub-$200 eight core processors when just a little over two years ago you would have to spend $1k with intel shows that the pace of advancement hasn't slowed all that much, and neither has the pricing behavior of those with the fastest tech.
