On the Anandtech forums a some users have released model numbers and specifications of upcoming and unreleased Intel processors. It's a list that is based on a photo from a power-point presentation, and seems the real deal e.g. Kaby- and Skylake-X processors. Interesting is that Intel is adding Core i9 processors.

Intel likely releases Core i9 procs to battle the AMD Ryzen processors and their pending (TBA) processor line. The top of the line flagship model will be a Core i9 7920X, this processor will be a 12-core part with 24 threads and that confirms all rumors and discussion we have had in the past few months. However 12 cores is less then what AMD will be releasing with their 16-core / 32 threaded Ryzen Whiteheaven processors.

Furthermore you are going to see a Core i9 7900X which will be a 10c/20t part. Then the Core i9 7820X, a 8c/16t part and then in the Core i7 line you may expect the Core i7 7740K and 7640K quad core processors. The Skylake X processor will all get a max 1MB L2 cache per core, that is a big increase coming from Skylake Core i7 7700k likely to increase IPC performance on the quad-core procs. The Core i9 processors are going to support quad-channel memory at 2667 MHz and will get a 160 Watt TDP, a maximum 16.5 MB L3-cache and 44 available PCI-Express lanes for inter-component connectivity. We think that in June this line will see an announcement, likely not at Computex. Albeit we do expect to see some stuff behind closed doors. It is also stated that the top flagship Core i9 7920X will be available as late as August. That again would validate an earlier rumor that Skylake-X biggest part being available move to August. Here is what the rumored linup would look like:
 

 
As much as we can argue and discuss, I would like to add a massive disclaimer, non of this information has been validated and thus please do take it with a grain of salt and as always, apply some common sense.
