I don't think you can blame a developer for making a game that doesn't last that long. Games, by their nature, aren't meant to last forever. Like movies or music.
That said, developers shouldn't expect cash for everyone who vaguely wants to play their game. Movies have television, music has radio, and games have ebay. Wanting to stomp out used game sales is the equivalent of taking your song off the radio. It makes it less popular, and less profitable.
As far as having DLC only within the next 5 years, I don't see it. Many, many people have trouble downloading a BR sized game over their home connection, and they always will. It'd be a huge hit to games like GTA, if they were only available via download, and I never see that fully happening. Especially as games get bigger.
I don't need your console war.
It feeds the rich while it buries the poor.
You're power hungry, spinnin' stories, and bein' graphics whores.
I don't need your console war.
NO NO, NO NO NO.
