Seems like they're preparing a new part of Time Temple.

if we consider the black mage as the goddess' personal nightmare, someone with a fraction of his power creating a sub-nightmare seems plausible, don't forget that, even if a person created a fake dream world withing maple, the black mage tore apart maple itself in big bang

This will probably make something happy, but thanks to all of us being in a dream, I expect we suddenly get ponies everywhere.

Also, still there hasn't been any news? They sure like to keep us waiting.
