I recentley emailed Lionhead to ask whether they were planning on porting Fable 2 to the PC. They replied with this:

Hi,



Thanks for your message. Unfortunately we don’t answer these kinds of questions by e-mail.



We’re currently very busy with the development of Fable 2 for Xbox 360 which will be released in October of this year. We have nothing else to announce at the moment.



We have regular updates of our games on our websites. For more info please keep an eye on our official site: www.lionhead.com. Or join the Lionhead Community @ link.
