WARNING: The passage below is just about total guessing and assumptions. You may find it very retard.
Each time Intel change their CPU line name, it means a big shift in mainstream CPUs architecture, which is the number of cores to be specific.
+Pentium to Core 2: sing core processor to 2-Core Processor
+Core 2 to Core i: 2-Core Processor to 4-Core processor.
Now, one of the first 2-Core processors for Desktop is Pentium D 850, which is released in 2005.
Then in 2006, Core 2 Duo made a debut, marked the shifting of mainstream consumers from Pentium to Core 2. That was 1 year later, which is 2-1.
The first 4-Core processors for Desktop was QX6800, which was released in 2006
In 2009, Core i7 made a debut, marked the shifting of mainstream consumers from Core 2 to Core i. That was 3 years later. which is 4-1.
According to that logic, the first 6-Core processor (which is i7-680) was launched in 2009. So 6-1=5 years later, there should be a next big shift. So we are talking about 2014. )
In 2014 (maybe very late, like December 28th 2014 or something because it's Sunday), Intel may launch something (Skylake I guess) that mark the shift of mainstream market from using 4-core processors to 6-core processors. The fact that Intel has not stated any specific roadmap for Broadwell on Desktop in 2014 may mean that Intel will release Skylake 6-core Processor in late 2014. Then in 2015, Intel will release both Broadwell on Desktop and Skylake on Desktop.
"Please don't let any Intel Staff read this post"
Again, that's just a total assumption.
What do you guy think?
