This seems to back up the rumors on the new PSP lacking a UMD player a bit. If they offer dual launches of titles, digital, and UMD, it would not hurt owners of the older units and save money on the amount of UMDs needed to be produced, shipping and receiving, ect.
I belive digital game downloads are the way of the future. It will save countless amounts of money on production, shipping, and retail sales. Just think how much Wallmart or Gamestop pays for each game unit.
If they cut out the middle man and just payed for hosting there product instead of shipping it they would really be able to invest more into development. And thus we will become beneficiaries our selves.
