Fable III is, erm, actually pretty good. It completely fails to revolutionise anything or deliver an engaging and believable fantasy universe, but the action is solid and there's loads of content. The Hut are currently the cheapest stockist around at £11.99, which is a bit of a steal as far as we're concerned. If you can stand the horrible VA.
On the other hand, there are some truly monstrous games coming out over the next couple of months. It's your call.
