There is a pre-beta version up for download somewhere in the TW discussion, but we've made a lot of progress since its release. We now have a scripter and the most important models have been taken care of, as have some scenes, so we're in a lot better position then we were, say, three months ago.
If you want to play the mod badly, here's my reccomendation - download the .903 beta version of M&B (it's got uglier graphics and is not quite as worked out as Warband, but fine otherwise) I think it's free to play since it's an old beta version. Then download the ASOIAF mod for that version - http://mbx.streetofeyes.com/index.php/topic,1257.0.html
. It should work fine, and it was pretty damn epic for me, it even has Valyrian steel weapons
. Some of my finest hours of M&B were spent playing that old module
