Just to clarify something

[Jay4J]

So I first read that Penumbra was going to be a 3 Episode game. And just recently I found out that frictional games weren't going to make the 3rd installment..... I have two questions,

-Why on earth are they not coming out with a 3rd installment???
-WHY!!!!!!!????

And please when you answer the question(s) be specific and give me a detailed answer, I don't want anything like "because they aren't" or something like that...
