BIG NEWS: Small Screen Star Wars

We may be able to shed some more light on the info indicating that Episode VII, VII, IX might happen. It may not be for a post-trilogy at all.
A year ago, we got our first report about the possibility of a TV show in the works after Episode III. We were not able to backup the info with other evidence, so it remained on the side and unreported... until recently.
We posted rumblings that Steven Spielberg might be involved in Star Wars post-Episode III and there must be something in the works, we got plenty of commentary. Then AICN posted the article about Pacific Digital and licensing agreements being extended, so many concluded that post-ROTJ films might be in the works. However, we also looked at our info from last year and believed we might finally have some proof of the initial report. We needed more.
We might finally have it. People we trust are telling us that there's a TV show on the design table. Instead of a Rogue Squadron series (which we first theorized some time ago), they may be looking at a post Episode 3 - pre Episode 4 about the rise of Darth Vader and why he is so feared in the OT.
We cannot confirm yet if the show is intended as live-action or animated (like Clone Wars). Since this is all in the early stages, it could change further down in pre-production. More as we get it - just thought you'd like to know what we're hearing.
