The question is, with Mattel as the master-licensee how does LEGO fit in?
While I've certainly heard rumours of reboots sets coming I wouldn't say it's confirmed yet. The article mentions licensing coming for both the classic films and the reboot and then rambles off some licensees like LEGO, Funko etc.
I'm 90% certain it's happening though.
