OK, first Duel is coming, then its not & now it is (sorta)
Duel has never been "cancelled"--just delayed several times in a row. Why, exactly, I don't know, but no, never cancelled.
& now Blade Runner is up in the air! WTF!
Is that Blade Runner the theater release? If it is, look out! 
There have been rumors about a new
Blade Runner disc for, literally, years. At least two or three. Apparently, it's tied up in "legal issues". However, Ridley Scott is a "friend of the format" (see
Alien Quadrilogy, Black Hawk Down (3-disc set), Gladiator, Legend: Ultimate Edition, etc.), and something will come out eventually, and it will be great, the be-all, end-all, for Blade Runner fans, I'm sure.
Also, what do we know about Battlestar Galactica?
'Cylon-Head' Packaging Is Going Away
Well, personally,
I don't know sh!t about
Battlestar Galactica, but I saw something about this at The Digital Bits just a little bit ago, myself. It sounds like they're just changing over the packaging from the big-ass molded robot head case, which apparently is quite unwieldy, to a more-traditional type of packaging. I'm sure the content will be exactly the same.
