The Shelve space is a concern. Nintendo needs to market the download service to where everyone knows about it. It is a major selling point that the other systems can't reproduce...and shelve space needs to be apart of that marketing.
I could see Nintendo designing download cards that you can pickup at the stores, perhaps able to be placed on the end shelf or something.
I could see download cards with pictures of famous Nintendo characters, Game Systems, and Classic Box Art. Stuff that shows the history of Nintendo on a simple card.
As well, I think Nintendo needs to design special sheving space for the Nintendo Revolution that contains banners advertising the Controller, and Download service. A nice slogan could be:
"The History of Nintendo, in one simple Box."
or
"Your gaming History, Your Nintendo."
or
"Your gaming memories, Your Nintendo."

I don't mean to say Nintendo can slack off and not produce and release games on a timely basis, or that they can ignore third party development. But I am saying that with the download service if you have slight delays in games coming out, it will not be as bad as it was during the Nintendo 64 or Gamecube eras because you can always download a classic game you never played and get your gaming fix. Does it allow Nintendo to slack off and leave us with huge gaming draughts NO. But, it does mean that the waits between games will be alittle easier to handle, because the Revolution will have more content available for it than we could ever have time to play. It just relieves SOME, but not all the stress of small gaming draughts.
