When will the next official modpack be released?

So Attack of the B-Team came out in February or something, but what I'm wondering is when will the next modpack come out. I don't mean a 3rd party modpack that someone makes, I mean the next official modpack that comes default with the launcher and is made by the owners of technic. Does anyone have any idea when it is due to come out, even rumors will be enough because I'm planning to make a server on it but I don't know what version of Minecraft it's going to be or when it will actually be released?

Would anyone be able to tell me when the next modpack is due for release, or even development?
