If existing Mac Pro customers can't afford a new Mac Pro with the same specs w.r.t. the state of the art then, yes, that means it is too expensive.
You can try all the double-think you like, but the
entry-level Mac Pro
is the replacement for the old Mac Pro and, even allowing for inflation (although that has never really affected PC prices in the past) it has doubled in price.
Ignore the 28 core, quad Vega II monster that was demoed - we have no idea how much
that will cost and maybe Pixar
will think its worth every penny - all we have so far is a $6000 entry-level tower with the spec of a $3500 PC
https://store.hp.com/UKStore/Merch/Product.aspx?id=4RX30EA&opt=ABU&sel=WKS - £3178 in UK tax (probably ~ $3500 in US) - definitely not a consumer PC, reputable (deservedly or not) manufacturer, 3.7 GHz 8-core Xeon W, 32GB RAM, 512GB SSD (but its not gonna cost $2500 to add a PCIe/M.2 SSD and 10Gb Ethernet
if you need those).
If you're getting $6000+ for an 8 core Xeon tower then you may need to research the difference between a $800 Xeon and a $2000 Xeon, or a $400 NVIDIA Quadro and a $3000 NVIDIA Quadro.
Inconvenient truth - the specs of that $6000 Mac Pro are no better than you'd expect from a $2500 cheesegrater (so, low $3000s after inflation) bumped to modern price-point-equivalent specs.
