3. Who is this "Lady K"? They're not going to release a demo for a game in a few months if it's actually 2 years off. A little over a year at most.
.
SE isn't using this demo in the conventional manner.Its not a demo indicative of a soonish release.
I bet its more of a litmus to test what ideas are working and what need to adjusted for the final game.
As such, the game will probably come a 1.5 to 2 years(roughly more or less) after this demo ,because they'll probably need to implement some changes.
