GameStop believes that consumers would avoid purchasing Microsoft’s next generation Xbox console if the decision was made to block used games.

“We know the desire to purchase a next-generation console would be significantly diminished if new consoles were to prohibit playing pre-owned games, limit portability or not play new physical games,” GameStop spokesman Matt Hodges told Bloomberg in response to the next generation rumors.

Hodges revealed that the company came to this conclusion based on a survey of its most active customers–the 21 million members of its PowerUp Rewards loyalty program.
