From researching a little bit around the net I have found out that Sir-Tech no longer owns it as they went bankrupt in 1998. They passed developing of Wizardry 8 to a separate company all together ironically called SirTech Canada. It was completed in 2000 yet they never established a publisher and distributor for the game. Yet a company in Russia published it and Electronic Boutique sold a US version for awhile.
The official website for the game is no longer working and from what it looks like the doors have shut forever.
So my guess is unfortunately Wizardry is no more.
I told the Overseer of Vault 13 I'd give everything to save everyone, and so I did, I saved them all. Since then I've felt loneliness.
