You buy white dwarf. They sell stuff. If you want it, you buy it. That's the deal.
Personally I'd like it if they gave me everything free. Obviously, you'd still have to pay. I want them to stay in profit so I can have more free stuff next month.
Apple's iPad sales do not contribute to GW's profit margin.
What have the flyer rules being in White Dwarf got to do with the ipad - yet? And no, I don't "know" about any future releases...
