If it's the X Hero your thinking of I think it's this one: ASUS Intel 1151 Socket Z370 Chipset Maximus X Hero D4 ATX Motherboard - Black: Amazon.co.uk: Computers Accessories
There were other Maximus models on your Amazon link...
I don't think there will be anything released very soon that will be significantly faster than the 8700K. There's talk of that 8 core Intel chip coming soon as a Coffelake refresh but I have some doubt's whether Intel are able to clock an 8 core as high as the 6 core 8700K...
What are the rumors on 10nm lately? Release date, potential chips etc? Someone told me that they'd rather wait for 10nm to mature before looking at high end desktop 10nm chip but I don't understand the full story. How often do you upgrade? If your already upgrading from Skylake then quite regularly? You could wait to see what Intel drop this year but I don't know how long you'll be waiting for 10nm.
All I can say is the 8700K is amazing and if your itching I'd probably go with it. Again I don't think the'll be anything significant compared to the 8700K any time too soon but I'll let some other users chime in who may be a bit more up on the Intel play... :)
