They did say that they will be bringing some sort of alternate rules server.
It is yet to be determined what that will entail However, as it seems that there are two types of servers in Korea that have raised rates, there could be a chance that that might be part of the new server.
I could imagine if after transfers open, they'll find a server or two that are too empty to justify keeping open. So close them up and use their hardware to start alternate-rules.
As far as things NCSoft has said, a new server has been mentioned the least (to the best of my knowledge just hinted at during a fan meet-n-greet). On the other hand, server transfers were officially said to be "soon" in 2004, have been listed as a feature... and still aren't here yet. On top of that, every indication is that NCNA can't hardly keep up with the current workload (website is C4-C5 era info, events left to run broken, etc.).
