All though Fable 2 was not on the PC, the 3rd one seems to be; http://www.amazon.com/Fable-III-Pc/dp/B002I0KO8I/ref=sr_1_7?s=gateway&ie=UTF8&qid=1284990369&sr=8-7
To be released on 10/26 as per Amazon, same as the 360 version. I am not sure there was anything officially announced in regards to a delay. I am not doubting it though.
Now, Fable 1 saw no support – that I could find. There weren't any patches. And if you ran into any game breaking bugs, you were on your own. 2 never saw a PC release. So, over all the MS Fable on the PC commitment is just scattered and unreliable. It's been like that from the very beginning.
Some publisher would prefer a console release over a PC release. I am sure a PC version will release. And if the claim in regards to the delay is that they are still working on it, it is bullshit indeed.
Personally, I will buy the console version, just not until it dips to the $20/$30 mark. 1 was great on the PC but awful on the Xbox 1, 2 was total shit over all and 3 may very well be underwhelming and not worth the launch price – like the other two before it. Plus, my "rig" may not be able to handle Fable 3, so I'll take the greatest hits version of console Fable 3.
