Paranoic much?
The game just came out this month and you are already thinking about when the servers are gonna close. xD
That's like 5 years from now at least.
Just have a blast playing it right now.
Besides, with the huge improvements and features that the Homebrew developers are making everyday, I won't be amazed if we end up having soomething similar to Wimmfi for the Wii U down the road.
