Did KCON just drop a hint as to who may be attending this year?

In honor of Presidents Day/George Washington's birthday, on Feb.15th , KCON, America's biggest Kpop convention, that takes place in California (and now New York) every year, tweeted a photo of a set of dollars bills where George Washington's face was replaced with the leaders of various Kpop group.

The photo featured Nayeon's Twice, iKon's Bobby, BTS's Rapmonster, and AOA's Jimin. Now while some just saw this tweet as a clever joke, many have been curious about the idols they chose to use, speculating that this may be a hint that AOA, iKon, Twice, and BTS will be guests at KCON 2016. Both AOA and BTS have guested in the past, but this would be a first for Twice and iKon, who made their debuts after the event was held in 2015. If we go by a tweet they posted on Jan. 26, they've only started planning for KCON 2016 last month.

However, with the amount of planning and scheduling that goes into events like this, I wouldn't be surprised if they actually started some time during the end of 2015, so it wouldn't be that weird if they already managed to confirm some guests. If we go by last year though, where they didn't start announcing guest until months before the concert, this supposed hint is a bit premature. If this is a hint, I have to give props to KCON, because this is really clever. I would also say I was excited, but I'll have to see whether these groups will be guests at KCON LA or KCON NY (if at all) before I get my hopes up. Anyway, what do you think? And what groups would you like to see at this year's KCON seventeen pls and thank you?
