Missing BGs on Cata and MoP

[Jakkre]

I have read that the Devs are working on a system that makes it possible to port the code and data of Wotlk dungeons to the other expansion.
Does this also apply to BGs?
I mean its been several years now since Cata was released and we are still missing SotA and IoC.
On MoP its even worse, out of 11 BGs only 5 are available.

I understand that PvE is important but pls dont forget about the PvP content...

So any news about missing battlegrund's?
I realy want to see some "new" bg's.
