A few weeks ago, Mice Chat was rumoring they would close it to add a Marvel M&G. Today they said that a Marvel M&G and stage show would be going in the stage area near Monster's Inc. instead. But they said that Disney Junior would still close and get a new show based on Disney Junior television. I'm glad to hear they were wrong with the former rumor, DCA needs that kiddie show. That being said, I think they said it would close in April. It's possible the calendar just isn't showing times yet. They're pretty bad with updating show times.
Edit to add: From MiceChat's weekly update
"The plan to infuse Marvel into the Hollywood Land area this summer continues to evolve quickly after the holidays. Disney Jr. is still planned to close this April, but the plan to do a Marvel stage show and meet n’ greet in that venue has been scrapped. The stage show and meet n’ greet will now take over the Hollywood Backlot Stage, the venue used for hosting high school choirs and traveling talent groups. When Marvel takes over that stage, a temporary stage for school groups will be thrown up in front of Stage 12 nearby. Disney Jr. will be re-purposed into a new toddler stage show still hosted by the Disney Jr. cable channel when it reopens later in the year."
