They really pushed us to solve the last few clues on that one day; if you look back at Ed's tweets, he basically guided us right there as much as he could without giving it away. They wanted us to solve it at that speed and I also feel like it is done, although I hope it isn't. It would've kinda been cool to see a game screenshot or something, but it was really fun nonetheless, and if there is any more to come, it'll be a bonus.
Their entire social media presence seems to have slowed down somewhat, compared to a few weeks ago when there were a barrage of behind the scenes photos being published from various old games amongst other tidbits. There have been a few surveys every now and again which I find quite interesting, but it seems like everyone at OWI have their heads down working on something else (Possibly that new Soulstorm thing)

. Perhaps there will be a second part of the ARG in the build up to the games actual release?
EDIT: Now I think about it, I don't think it'd be out of the question for the 1029.io to play host to some mini-puzzles to unlock screenshots etc. once Soulstorm has this "Official unveiling" Lorne has spoken about. (The unveiling was meant to have been done by E3, but it's coming within the next few months according to Lanning) We'll just have to sit tight and see.
Until then we must keep sharing pictures of dogs that fart like Oddworld characters. It appeases the gods.
