A Canadian web store is listing a Ryzen Threadripper 2990WX processor and does so for a price of just 2399 CAD, that is 1835 USD converted. Quite a bit of money for sure, but for 32-cores, I mean that's value at less than 58 EUR per core.

The price actually would make sense as it is roughly double that of the 16-core Threadripper 1950X. Of course, with all prices that get listed prior to a release, we're not sure if it'll stick. The 32-core and 64-threads processor is based on a 12nm LP process from GlobalFoundries, also called Zen+.

The 8-core dies are based on what is called Pinnacle Ridge architecture, four of them placed on the multi-core chip package. The new 32-core processor fits into the current SP3 socket with your existing X399 motherboard, accompanied by a firmware update you should be good to go. Again, it has four eight-core dies under that heat spreader, this new 12 nm 8-core "Pinnacle Ridge" dies to bring the advantages of Precision Boost II and XFR 2.0 into play.  

The Ryzen Threadripper 2990WX is listed by the webshop with product ID YD299XAZAFWOF. In the specs it is confirmed to be the 32-core part, and being listed with a 250W TDP.
