Given WB's recent record with the DC universe, I'd be extremely concerned with this.
It's not as if The Matrix wasn't already milked for every penny it was worth, and then some.
It's not a Batman or Spider-Man sized brand, and doesn't really warrant a reboot/remake.
The one scenario where I'd be a little bit more interested, is if they made it a TV series on Netflix, and used it as a Black Mirror type show to explore different sci-fi ideas, while wrapping it up with the Matrix universe. A bit like the Animatrix was, which had some misses, but a couple of interesting hits.
