What does Lordaeron mean for the other realms?

So it's my understanding that Lordaeron also brings a brand new core.And while I will play on the realm and probably love it I'm curious what does all this mean for the other realms,especially the Cata and MoP ones.

We will continue with their development. Actually, there has always been a team of developers solely dedicated on each expansion.
