I don't know how much of a fight the industry is willing to put up, because in trying to kill brick and mortar stores...there will be caveats to doing so. Things like Limited Editions do make alot of money for the right developers, especially if we're talking about ones that can go over the $100 mark. If the industry goes all in on this, and tries to essentially suffocate Gamestop, as well as now other stores that now do used games as well, the push back could get ugly.
I just don't know if the industry in general is willing to go all in on fight like this, because it could hurt their bottom line.
Gamestop seems to be gearing up for the impending digital warfare, so if they get more time...they could end up in a better position than Blockbuster did.
Which is to say, not become a Museum of the '90s.
