There is a huge difference between speculating on fabricated and false information and making statements based on the released information, which at this time is factual.
Er, no, it's not factual. For it to be factual, it would have to be demonstrably true, and I'm pretty sure that none of your 'facts' can be proven at this point.
I would certainly agree that the information you posted is more evidenced speculation than some of the posts, as it's based off the current developer intentions. Whether they can deliver on it, or whether they change their position is something only time will tell.
Ritual is planning on releasing the original SiN over Steam before SiN Episodes.
Is this supposed to be a Source engine version? Or just the original SiN? If the latter, I'm not sure why the re-release of a 7 year old game would really be that big a deal at this point.
