D&E are having success as a duo unit right now, but is Super Junior coming back as a full group soon?

That's what Leeteuk said on his official Instagram, as he posted the above photo with the caption, "Comeback confirmed! Coming back next month.. #comeback."

He posted another photo on Instagram of fans dangerously leaning on a ledge to see Super Junior and he wrote the caption, "Guys it's dangerous!!!! Don't do that!!! Your oppa's are coming back so save your enthusiasm!!!..^^ COMING SOON.."

However, one thing to keep in mind is that this was posted on April Fool's day in Korean time.... so... what do you think fans? Is Leeteuk pulling a prank or could he be serious?�
