Problem is.. I really don't see why DMM would want to create it's own separate English version, starting from the current Nutaku content instead of from scratch, and expect new players to go in and dump a lot of money for Himes but miss out on a TON of event weapons. So to be honest, the plan to launch it's own English version, ending up with two of the same thing in the "global" market, doesn't sound like a good business plan...
Edit:
Received a reply from DMM support, apparently they can't give an answer as they are only able to respond to things related directly to DMM Games platform, in this case they can't answer about what will happen to Nutaku's side and it's players. So now all that's left is to wait for KamiPro's own support to give me a reply, but from the look of things, I'm likely to get the same "answer". So guess the next thing is to see whether or not Nutaku's "without any changes" refers to 0 updates 0 events=no change, or they will maintain and update the game as they have been doing so.
If anything, it sucks that there is a high likelihood the English version on DMM "might" have the fixed jewel rate up and better raid servers... And cheaper SCs for any non-Japanese residents.
