I agree it can't be a reboot. Has to be part of what we know.
I watched the very end of the last movie last night. The little girl asks the Oracle if they will ever see Neo again and she says something like "I think we will". So that left it open to easily do a sequel. I'm not sure who'd they'd fight since they have peace.
how could the studio redo or relaunch these movies without the wachowskis
The Matrix is a perfect diamond of style and substance and its timing was impeccable. It was so unique that even its creators couldn't run with the idea so its a tough gig to take on for sure but I`d give it a look.
