MapleStory Europe getting Kaiser soon?

I can't wait to see EMS break if they try to do such a megapatch. Do you realize how long that maintenance will have to be to change so many things?

I'm pretty sure the size of the content that's coming with the patch shouldn't affect the length of the patch.
They have already changed and tested (hopefully) all of their features and if they are content with the bugs fixed, they push it to the live server. AFAIK, all they have to do is test if it's running properly on their live servers or upgrade the servers as needed and they turn the servers back on to the general public once they are content with their testing.
