This Bleeding Cool "reporter" fails on one big count in particular - 20th Century Fox Television still owns the television rights to the Firefly
name and characters. Joss wouldn't be able to do a "reboot" on the Science Channel, or any other channel, without first acquiring those rights, and it seems unlikely 20th would sell.
Also..."planned Firefly reunion movie"?
The reunion documentary has been under discussion here
[...] Dark Horse will be doing post "Serenity" comics showing what happened to the crew after the film ended.
It's about damn time. This is exactly what I've wanted since Dark Horse first started publishing Serenity
comics. That said, the prequel comics have been a disappointment, so I hope these post-movie comics step up their game.
