Microsofts conference was rubbish. Fable 2 is being released in an episodic manner on Live, and Fable 3 is out next year. That was it...
This is the problem a lot of people are having. It WASN'T a Microsoft conference. It was a Lionhead announcement briefing. That's why only Fable was mentioned.
Ah, the site i read it on listed it as just the Microsoft Conference. And considering Molyneux is Creative Director of Microsoft Game studios for Europe, i just assumed the site was right.
Edit: and according to the official schedule it was both a Microsoft and Lionhead conference
It is quite strange how it was advertised, but I think they probably said 'Lionhead/Microsoft' because of Molyneux's position within Microsoft. I thought they might have taken the opportunity to try and gain some ground on Sony after their successful conference, so I was a little surprised, too.
