First Hint Is Leeteuk's Instagram:

Teuk's tweet: ..I will become even busier..Lets work hard!!!^^..#soon#comingsoon

The hashtags and him being busier can be related to the so called July album

Members Going To SM Building

They would have no reason to be there unless they have a upcoming schedule or something 

Yesung Instagram: We start up and go ahead now ? #SuperJunior #VroomVroom

Posting old album pictures all of a sudden?

Hyuk's tweet: All right everybody!! Are you ready to have a hot July? #July #hotsummer #supershow #encore #somethingspecial #Are #You #ready

Also changing hair color with other members?

Fans are also pointing out..

"alright/all right" on eunhyuk's/donghae's tweet and an "alright" sign from wookie 👌 is this a hint? or am i just overthinking 

Fans are also pointing out that Alright was used with the same sign Ryeowook did during Mr.Simple

Yesung posted photos of 4jib & 6jib. 4jib they went for an y concept and 6jib was called Y free and single..

Yesung: SUPERJUNIOR ... Loading ..

This is what our fandom has came up with so far! If more hints are given Ill update with a new chapter! What are your thoughts?
