"What is real?" Morpheus asks. "How do you define real?"

We may or may not know what is real or not, but what's certainly real is The Matrix will be rebooted.

It's been confirmed that Lana Wachowski will be co-writing (with novelist David Mitchell) and directing Matrix 4.
 
Lana will be working for the first time without her sister Lilly. 

Keanu Reeves will reprise his role as Neo and Carrie-Anne Moss will reprise her role as Trinity.

Reeves has already read the script for Matrix 4 and is "excited," saying that "it's very ambitious", in an exclusive interview with Entertainment Today.
