I don’t know if they showed a new planet, but it looked vaguely like place where Maz Canata lived. Maybe she had a bunch of other Jedi junk lying around. Then again maybe it’s just a generic forest world.
I assumed it was a vision as soon as I watched it and I suspect most people did. Not really a slip up on the official discussion leak.
It didn’t stop all the evil clone discussions.
I thought it might be Endor. The hippie festival Rey and co. come upon looks like it could be an Ewok thing?
Didn’t some of the early concept art for Ep 9 show Yavin 4? That would be my guess as to where the ‘new’ Resistance base is, and where Rey is training with the probe.
I’m assuming the Death Star chunk crash-landed on Endor and maybe wreaked enough ecological damage to create barren areas, hence the landscape behind Rey and co. as they advance upon the festival. The Ewoks may be gathering to combat the great evil that has been spreading from the DS wreckage since the battle 30 years ago. Rey could simply have gotten the remote from the Falcon where Finn tossed it aside in TFA.
Or has it been established that it’s the first Death Star in the ocean…?
