Another possibility is that Tim as hinting at something which was in very formative stages and that the dissolution of InterMediaLab (and, for that matter, Televirtual) was just a result of the recession.
I'm reminded of the speculation that surrounded certain sections of the gaming community a few years back about a possible sequel to
Superfrog following the eponymous hero's appearance in several
Worms games. In fact, Martyn Brown (Boss of Team17, the company that developed
Superfrog) actually let slip that they were working on "something very bizarre with him" and several websites reported on it. However, nothing came of it and Brown later said in an interview that making a
Superfrog 2 was "just a concept... they are created all the time".
I think this would be something similar. I'd have a difficult time were I to believe that Tim actually had something along the lines of, say, a potential new series of Knightmare, or even a way to do something new. He only made one, very vague, post, which could have been made on a whim
sans prayer. He could have just had a vague idea inside his head. Just a concept? They are created all the time, after all.
My reckoning is, Tim never would have anything to stir us up in 2009. He may have thought he would at one point, hence the post - but I'm pretty sure he actually didn't get as far as he (we?) thought he would. As has been said, InterMediaLab actually haven't done anything recently - well, have you seen them do anything? At the very least, Televirtual worked on their V-Actor thing, but I've not seen InterMediaLab doing
anything! - and it's entirely conceivable that, in the aftermath of the credit crunch, they decided the only viable thing to do would be to close voluntarily.
Sorry to be a pessimist, but I think that there isn't anything to talk about, and there's no company to provide us with it, either.
