All new games will have digital download option. Most wont even have a physical disk option. The few that do offer the physical disk will surely charge more for a re-sellable disk. Physical disk price will have to be higher than DDL to cover retailer margin. Digital releases of new games are already being released sooner, cheaper, with more options than their antiquated physical equivalents. New game sales are off an astonishing 25% lately....and this is before the new consoles.
Used games - all the old titles are going to be offered DDL at very low prices. Don't believe me?? Go shop at Steam this week; or Xbox Live; etc. There will be a lot fewer of the new physical games bought at retail (see above) and those that are brought in for re-sale will to compete with publishers who will lower prices on old games. Hard for GME to buy used games for inventory when these are competing with DDL versions.
New Hardware - Good luck with that. Competing with Amazon, BBY, etc. Nintendo about to die in US.
Used Hardware??? - Oh please. Everyone from Apple, to BBY, to Redbox is doing that. Is GME going to stock up on PS3 and xb360's? hope they have plenty of warehouse space.
