Well, yeah, but for one, he went missing over a year ago with absolutely no signs of life, so compared to that, a real stream 3 months ago is confirmation that he is at least alive and he still thinks about this game.Nomo hasn't been sighted, since the post you quoted as about Nomo's last steam, 3ish months ago.
There's still been no word (AFAIK) after that, so assume that he's still MIA.
Also, the current patch cycle is 8 months long, and as irrelevant as a 3 months old appearance seems, that still means that the stream is newer than their latest patch.
