The HALO universe isn't something to which I can say, I have interest in but I understand it. It depends on the stance that they take. The web series 'Forward Until Dawn' was actually surprisingly well done in my books however one thing is always in mind. Cost, it cost roughly $10 million USD to produce 'Forward until Dawn' and that was 5 fifteen minute episodes. The only way I can imagine this being done within the constraints of TV budgets is set during the separatist conflict (human colonies trying to break away from Earth), that way you have mostly human characters and enemies, because having the aliens (Covenant?) would be way to costly in both practical and CGI effects for any length of time on screen.
I could be wrong, but I go off track record and Spielberg, well he's off the tracks and up a cows arse in my books.
But I hardly use it...it is there mostly for my best buddy when he comes by and we play Def Jam Fight for NY and Test Drive and a couple of other games. I play games on my PC when I want to play a real game. 
.He's dead on and sums up the announcement nicely.
very true. On second thought I would approach this with caution then
