Damn fine idea sir......but Ill be utterly shocked if it happened. To me, the fact that they shut the server down tells me that they were interested,and likely already planning, a Vanilla server. But at least they are trying to have reasonable discussions with their fan base as to how it will be implemented. They certainly didn't have to do that.....
No, the problem is that they're often charging the players to play on these private servers(in one way or another). Running a server isn't free and it requires admins and people to keep it up through maintenance . They don't have a license to run a server from Blizzard(activision or whatever is in charge of that). It's not like this is the first time people have made private servers for games, some companies go in very hard to crush these just because people are making money off them through donations and what not.
I am pretty sure they said the exact same thing for the FFX remaster being PS3 exclusive, so don't read too much into any of it yet.
... you've not met Deep Silver before, have you?
