So, as I'm sure most of you all know, the internation version of Gunz the Duel is closing as of May 15th.
It's the only version I've played, and the last time I played was around two years ago.

My question is:
Will this version of Gunz the Duel still be up and running? http://gunz.ijji.com/

I plan to download and install it fairly soon, if it will remain functioning.
Also, what are any differences between the versions?
