As I said in the post, Portal for me is more like an experiment of Valve, maybe that's why they didn't develop too much a concrete story but they left little details to theorize and to wait for a new release. Thanks for the comment!

It has a lot of details of its history but the truth is they are either minuscule or you have to think hard to decipher them, and I think for me that's what makes it even more interesting. I do think that someday there could be a future installment, if Half Life 3 comes out in 10 million years, Portal 3 has to come out.
