GW are giving the indies the ones they're getting for free, so it would have more profit per unit too. Indies I've spoken to would much rather have fifty of the things to sell than two that are so ludicrous they either have to ebay scalp them and take a load of flack or try and auction them off or something for little reward given the effort.
I have no idea what GW was thinking here.
Well yeah there's that too, though I'm less worried about GW's revenue here- they're well resourced. Perhaps GW just saw the good PR story and didn't think through the full implications for indies in giving out so few (and that they could have done this making a little direct profit for themselves selling the models onto independents)?
