StingingVelvet: Yeah, Planescape is in rights limbo hell... I wouldn't expect to see it release anywhere legally any time soon. I have a feeling Atari might end up with the rights, and they don't digitally release their catalogue anyway.
Aparently not as CD Project rereleased the
polish localised version on 22nd of may 2009. Box has ATARI logo as did Icewind Dale and Baldur's Gate collections ATARI rereleased few year back. Planescape was also available at gametap until recently.
As far as I can see Infogrames/ATARI own the rights to Baldur's Gate and Icewind Dale series and Planescape: Torment game. Most likely they purchased the rights durring interplay's financial difficulties like Bethesda did with Fallout series. Infogrames/ATARI also hold exlusive licence to develop and distribute games based on Hasbro franchises (AD&D among others) until 2016 with further 5 year extension if Hasbro is happy with the results. ATARI has also stated they will revisit Baldur's Gate series (among others) after 2009.
