I still don't understand why Intel doesn't adopt i9-xxxx for the enthusiast platform. It would distinguish a completely different line, and make it sit apart from the i3, i5, and i7 platforms. (sorry for the random tangent)

I am interested to see what the broadwell will be able to accomplish compared to the haswell, and not surprised they are going to delay strictly due to the fact that the competition isn't there.

Well guess i wont be waiting for broadwell...

One can completely redact the Projected Date aspect of the Intel Roadmap because there's no competition.
At least Intel so far cares about it's reputation and isn't producing junk for a high price. Again, so far.

Information seems a little loose... "six or eight cores", I'd think it would be extremely unlikely for Intel to only launch hexcore chips when the eXtreme edition is up to eight. If Broadwell-X was expected to launch Q4'15 then delaying it till Q1'16 isn't much of a delay anyway. I'll be more curious to see if the date starts to slip further. 
 
As for performance increase, it's just the same core so it'll be 0-5% unless they up the caches. I'm more hoping it will translate into cheaper 8-core chips but will have to see...

The article States Broadwell-E meaning the replacement to Haswell-E, also meaning it should replace the hexcore because it will be the extreme (hence the -E).

That would also have Haswell-E out for approximately 18 months depending on the release if they push it to late Q1, meaning everyone will be ready for a new -E cpu to be released.

Makes me happy to have gotten my X99, and i believe those cpus also work on the same 2011 v3 socket, so easy upgrade path for me later.

22 months separated Sandy Bridge-E and Ivy Bridge-E, while 17 months separated Gulftown and Bloomfield.  
Considering the absence of AMD in the upper end and only competing with their own unlocked mainstream, I say Broadwell-E is on schedule for 2016, my guess June.
 
As for the idea of more than 8-cores, not until Cannonlake-E.
 
Presler flagship was a 2-core
Conroe flagship was a 2-core
