Planescape Torment and Legacy Of Kain Coming to Steam?

It may sound like the hobby on a crazy person, but someone has to do it (I guess). Over on Reddit, Jack Nash posted some information found in Steam about Planescape Torment and Legacy of Kain games. Apparently there was a database entry for these games and some Kain themed costumes for Guardian of Light.
It would make sense for these games to be on Steam considering they are classics. They are already on GOG.com, but some people like to have their games on Steam. I personally never played these games and would love to give them a try even if they are older. It would be fascinating to see them, and understand what is great about them. Have any of you played them in the past? If so what are your thought on them coming to Steam?
