I don't think it will easy to overclock these if true

Plans are subject to change.  I like the line:

 the company has changed its plans and will release unlocked versions of its “Skylake” CPUs in the third quarter of 2015

 
I started to formulate a theory only recently, what if AMD's departure from pure CPUs was just a ploy to get Intel to isolate overclocking to another platform and take over the void of budget overclockers themselves?  I could have worked, and takes at least a month for Intel to react (time it takes to fabricate and distribute around the world to retailers).
 
It is funny how anyone suggests AMD isn't competing when Intel changes their mind like this, what on Earth could be so worrisome to affect their bottom line?  Who would they lose budget overclockers to?

That is a interesting theory Lehpron. Maybe AMD saw something in Intels Anny Pentium release data that could benefit them. It makes me think of the Celeron overclocking craze we went through. Those were fun times!!

Check out Intel's price list (400kB pdf), they are currently offering over 150 SKUs in seven sockets (not including Xeons), why?  The point for competition is to steal sales and the easiest way to do that is to attempt to fill gaps in another's portfolio.  Seems like Intel has preemptively tried to fill every gap they have, except they still have gaps if AMD is able to maintain their tiny share of the market all this time.
 
Intel calls X99 their HEDT (high-end desktop), therefore even their Z-chipsets aren't high-end, which makes everyone else 'budget overclockers'; so no, I'm not just talking about Pentium Anniversary Edition users or those interested in A10-series as those under threat by Intel's actions.
 
AMD's last few high-end debuts were priced to meet up with Intel's Core i5, they aren't interested in competing with any Core i7 model.  Had Intel isolated overclockers to X99 and its successors, the $200-ish i5-K SKU would go extinct, forcing the overclocking minimum to the $300-range or higher.  Who in here that bought into Z-platform would be comfortable being forced into X-platform just to overclock?  If not, then AMD has a place for you; or at least had if Skylake-K wasn't coming. 
 
If Zen was meant to be AMD's rope-a-dope after bluffing an absence, adding in that Intel has been leveling out their IPC as if AMD gave up, then the stage was set to take over the majority of Intel's overclockers that tend to buy i5-K and weren't willing to pay twice as much per processor in X99.  But Intel isn't dumb; they did indicate a Z-chipset for Skylake in most leaks roadmaps.  Therefore, I saw it as a contingency, just in case AMD pulls a rabbit out of the hat.
 
AMD doesn't have to have anything better than Intel.

Having the same TDP rating doesn't imply anything about specs, it only exists so Intel can debut any number of processors for the same platform and not worry about cooling, since TDP can dictate which cooler to use.  You're right, actual TDP should change with the shrink and specs, and TDP wattage is different from power consumption, proven by the Intel link at the bottom of my sig. 
 
Historically, Intel has added more cores once every third series/generations:

• Quad-cores were high-end from 65nm Kentsfield, 45nm Yorkfield and 45nm Bloomfield (all were 130W TDP).
• Six-core models were high-end with 32nm Gulftown, 32nm Sandy-E and 22nm Ivy-E (also all 130W TDP except for 150W i7-3970X).  
• Therefore 8-cores will remain the highest-end consumer i7 model from Haswell-E, Broadwell-E and Skylake-E, all could be in the 140W rating.  Only one Haswell-EP Xeon has a 160W rating, the E5-2687W-v3, a 3.1GHz 10-core model.

It is Cannonlake-E that we see the first opportunity for more cores, somewhere out in 2018-- unless you believe AMD will pose a threat to Intel before then?
