Agreed, 1151 has to be made available first along with skylake cpus to benchmark for any real world comparisons. Socket 1151 will bring some potential changes, it's up to the motherboard manufacturers whether they'll make use of it all. Current 1150 has 16 pcie lanes, 1151 will have 20 lanes. The boards will be a bit different since they're moving the voltage regulator from the cpu (fivr) back to the motherboard. Most 1150 motherboards have just 1 m.2 slot and/or sata express, the 1151's will be able to have multiple m.2/sata express. Likely higher number of usb ports and sata ports as well. Some 1151 will support ddr4 ram while others will support ddr3L (low power) so-dimm memory. Just because all these features are possible doesn't mean every board will offer them. I'm sure high end luxury boards will offer the most while lower end budget boards will leave some out.
