Isn't it possible that the response they give to consumer requests is just like E*. Ask E* if Food HD is coming, and you get a blabbering response with no answer; then two days later it goes live. E* simply does not want to say anything about what they are planning.
Maybe Sci Fi simple does not want to raise expectations about something they are thinking about, but aren't ready to implement, for whatever reason.
I sort of look at it as if the HDTV world is spinning right now, and change is occuring so quickly that its hard to know what will come out in HD and when. Yes, I desperately want Sci Fi HD, but it aint happening quite yet.
... Until all of a sudden Scott posts a surprise exclusive message in the Pub about its arrival. I look forward to that day! (Ok, I can dream!)
