"I own a PSP Go but don't want to buy LittleBigPlanet, for instance, as I can get it 20-percent cheaper on UMD from Amazon and could resell it once I'm finished with it," Burton explained. "But if I download it, I get no discount, and no chance to resell — how annoying is that?"

While he describes it as annoying, Burton actually think the problem flows much deeper. He added, "I'm betting on Sony making PSP Go games much cheaper than the UMD versions, or the PSP Go will die."

The problem is, at what point do retailers start burying Sony's stock when the Playstation Store undercuts them? It just highlights the problem of switching to a download model while retailers still possess a lot of power.
