Capcom has clarified its position further in a brief FAQ style post on its forums surrounding the Resident Evil: Mercenaries controversy that's come about because the game doesn't allow users to overwrite their save data. Essentially, what's going on is that you can unlock content a single time for each cartridge, and after that, it's always unlocked. Many gamers immediately assumed that this was to make the game more difficult to sell once it's finished. After all, who wants to buy a cartridge with all the content unlocked? Or rent one?
In Capcom's post they denied that this is the case, saying they had no intention of "lessening the experience of the game."
