You think so positively.
I can't imagine what the forum will be like in a few years. Not entirely sure if the whole forum would be completely run-down considering it's used for things other than Animal Crossing (and New Leaf was a huge success). If Nintendo stopped making Animal Crossing games, then maybe it'd become just a gaming general forum, I don't know. Obviously nothing lasts forever though.
Honestly, whatever the forum's like in the future, I just hope I can stay in contact with as many friends that I've made here as I possibly can.
