Its only a teaser of 3 episodes on blu ray as taken from the o-neg according to that trailer.
I guess the whole thing being done would depend on sales or if they can get a syndicated tv deal for a zillion stations to show it.
I mean not many people are going to pony up money for encounter at farpoint and those other 2 episodes. Its not like this is the best of both worlds or yesterday's enterprise.
If i recall the original series was only afforded by the HD-DVD people funding it.
