Not sure what the business model would be here.
IDW could sell it to us for 3 or 4 pounds a pop or whatever the price is. Or they could arrange to give it to us in a way that generates no additional revenue. They would presumably expect to get paid, so Rebellion would have to pay them for it, to fill a slot they usually use with material they already own. Given they have spent lot of maoneybacquiring the Treasury of British comics stuff, I assume they have plenty of stuff to fill floppies with.
