Why did intel just add 1 pin to the 1150 socket to make a new one

Why did intel just add 1 pin to the LGA 1150 socket. I bought an LGA 1150 boardfor $120, and I am satisfied for now, but in a few years I am going to have to replace my board becaude it would only be compatible with outdated CPUs. I would just like to know why they would do that.

CPU sizes have changed over time along with the sockets they go in. Its just the way it is. CPUs have changed over time, think of all the advances in architecture and design, things like multiple cores - the CPU of yesterday is going to be different from the one of tomorrow, socket sizes have to change as a result.

It's not just the extra pin somewhere like AM3 vs. AM3+. It's the layout.

As far as why, it's likely a change for use with streamlined designs.

A new architecture requires a new interface. As shown in the link by Justicinacan above. They didn't just add a pin so you have to buy a new CPU.

Skylake moves the voltage regulator back to the motherboard, where on the Haswell and Broadwell chips it was integrated into the CPU. Even if all the other pin-outs were identical, that change would require an entirely different CPU socket simply because if they didn't do that then Skylake CPUs would have no voltage regulator.
