I sincerely doubt that this is going to happen.  Emphasis on "rumor," of course WB would love another Matrix trilogy, who wouldn't?  Would I want to see the Matrix in native 3D?  Absolutely.  Especially after [i[Man of Tai Chi[/i] showed me Keanu doing martial arts again.  But really, what more can this series do?

I watched the original a few weeks ago, and it really made me realize how timed it was to the 90's, where we thought in the back of our heads tech was about to wipe us out, where we weren't sure of the levels of gov't surveillance were... computers and the internet were wide-spread enough that we all knew about it, but it wasn't mainstream enough for everyone to truly grasp its' limits.  And the bad guys... at this point in history, the men in black were everywhere: they were the bad guys in the X-Files, they had a humorous movie inspired by them, and they're the basis of the Agents as well.
