1) Who's Next 11.21 - 21:00

This is the most obvious and there should be no if's, and's, or buts. November 21, at 21:00 hours only points to the group 2NE1 that is housed in YG Entertainment.

2) YG Entertainment's main producer

We should also focus on producer Teddy and watch his movements very closely because, Teddy and his friend made a new label under YG Entertainment. Ever since 2NE1 debuted, Teddy was right by the groups' side and making hit songs for the girls as well. Not to mention his close relationship with each of the 2NE1 members. With his new label set up under YG Entertainment and to promote his new label, it's a great opportunity and timing.

3) CL's American debut delayed

The announcement of CL's debut in America made major headlines. But as it was time for CL to actually debut, the dates kept getting pushed back. Speculation is that 2NE1 was prepping for their "secret" comeback, hence delaying her US Debut. 

4) Statement from Yang Hyun Suk + Contract

In the end of 2016, 2NE1's contract will come to a close. As of right now there is no news on whether 2NE1 will resign or even extend their contract. Thus bringing worries to the fans. On Oct 3rd Papa YG stated "As of now, we are focusing on CL's American debut. After she does well [in America], we will think about [plans for] 2NE1."  He added, "2NE1 is contracted until next year." This brings up an interesting thought, CL's American debut kept getting delayed and if 2NE1 makes a comeback, Yang Hyun Suk will know exactly what to do with 2NE1, depending on their performance, from a business side point of view.

5) Mysterious post on CL's Instagram account

A blurred out image with the caption "ALL OR NOTHING" was posted on CL's account. "ALL OR NOTHING" was the title of their last album. It's also speculated that the blurred image features the 2NE1's members. The image has been deleted now and replaced by numerous other photos.
