Perhaps they're taking their time to get it just right. With only three 'action' poses really possible (bending bow, resting bow and nocking an arrow) I'd be tempted to make specific torsos for each pose. You lose the versatility but gain quality of pose.
100%. I think they would sell too but, like you said, that is all down to how convincing the posture of the miniatures is at the end of the day.
I've got my fingers crossed as I would certainly be buying ten or more boxes!
If Men at Arms on Foot and Archers are in the offing then Crossbows, Pavisers and the big one, Mounted Men at Arms would almost certainly have to be in the offing at a later date too.
