According to Benchlife the new chip will be showing off up to 10 cores/20 threads.
This will be the first deca-core on the commercial market and it will use the same x99 motherboard. Here is the range that Benchlife found. There is no guarantees that it is more than a rumour, but it is fairly specific.
Or if you cant find the your way through the big advert written across it here is a tidied up table.
