YG Entertainment planning for something on April 19th?

For visitors to YG Entertainment's website on the 16th, they would have been greeted by a sentence laid against a black background that wrote, "Let's go crazy!". And if you go ahead and click on that, you will be directed to a me2day blog that wrote, "April 19th, 10am" and the same message. Fans are apparently going crazy and speculating on what's being planned by YG on the 19th. In response, YG expressed, "This is part of our teaser marketing so we cannot reveal anything more. Please wait until the 19th." Having announced comeback plans for Gummy, 2NE1, Big Bang, Taeyang and Se7en earlier in the week, fans are suspecting that this message could be linked to either one of them. Excited much and who do you think it might be?
