October is going to be an interesting month, next to the Radeon RX 5500 release, and new 1650/1660 cards from NVIDIA. Next to that Intel is planning to release a number of new processors, as well as Cascade Lake, is making an entry.

The initial X299 motherboards compatible products are 10-core/20-thread Core i9-10900XE. Then there will be a 12c/t Core i9-10920XE at ~ $700. Intel will also release a 14c/28t i9-10940XE for roughly $800 and then is closing with an 18 Core i9-10960XE at $999. You'll notice that Intel is severely dropping price in order to be competitive with AMD, Intel is going for 50 to 60 USD per core for the HEDT platform. Interestingly enough there is no mention of a 16-core model. It is expected that the single-core turbo will ruin towards 4.7/4.8 GHz.

Cascade Lake gets 44-lane PCI-Express gen 3.0 lanes and offers quad-channel DDR4 memory up to 256 GB with official support for DDR4-2933 memory. Your X299 LGA2066 motherboard will be compatible with a BIOS update. Much like what AMD is going to do with the new Threadrippers, Intel will aim these chips at PC enthusiasts and content creators. As things look right now, October 7 you can expect announcements with market availability in November.

Update - intel just gave the thumbs up to post these slides due to the leak:
