So although the Epilogue is currently going on, there is suspicion that BTS might be planning a world tour in early 2017.
Early rumors were reported by @DailyNamjoon on twitter.
This matched with a recent campaign that is being run by a music and concert websites known as My Music Taste. Fans can advocate for certain artists to visit their cities by voting and completing certain tasks. Although this site may just seem as a way to look at demand for certain artists, fans noticed a recent post on their Instagram.
The post basically shows that MyMusicTaste has partnered with BTS to discuss concert venues, and thus may lead to a world tour in early 2017. MyMusicTaste has already partnered with groups such as Block B and IKON, so I think it is safe to confirm the possibility of there being a tour in the VERY near future.
