Please don't pretend backwards compatibility for games is as simple as backwards compatibility for movies. Converting a movie only requires that you preserve the audio and visual streams. Converting a game requires that you emulate the underlying hardware or else write a complex program to automatically convert code optimized for another system on the fly to the new one.
Sony and Microsoft didn't remove backwards compatibility for next gen consoles because they are mean money grubbing bastards - Any halfway intelligent businessman would see giving existing customers a reason to stay enfranchised is a great idea - they did it because adding it would have required them to increase the cost of the console to a level the consumer would be unwilling to pay.
Sony should know - They did this once with the PS3 and it was one of the reasons the PS3 was initially such an overpriced machine and failed so badly at launch.
I came here to say pretty much the same think. While preservation of games is an important endeavour, it is infinitely more complex than preservation of movies, because its intrinsically associated with the technology it runs. While preserving a movie requires preserving the video and the audio synchronized with it, preserving a game requires to preserve (or reconstruct) the hardware that it was built to run in, including parts that, are likely, no longer built.
Movies don't have that problem. I don't need a pianist to be able to watch A Trip to the Moon, nor do I need a drive-in theater to see some exploitation movie like Ilsa... It would be a nice curiosity, but its not like its required by the medium and its not possible to reproduce in other way. There are some exceptions, of course, like watching "Scent of Mystery" in my house or reading "House of Leaves" on a kindle, but 99.99% of the content of other mediums is easily preservable because our way of experience it doesn't evolve with it.
Games, on the other hand, need the hardware to run... there is no way to run E.T. or Wii Sports without the original hardware (unless we count emulation, a process that runs entirely on the part of the consumer, since the publisher doesn't want/doesn't care/simply can't do it itself). To expect otherwise would require
a) that console manufacturers and technology holders (and everyone in between) would compromise to never stop producing the components to run certain generation of games (good luck trying to force Commodore to make more Amigas); or
b) building each generation, literally, on top of the previous one. So, the Playstation 4 has to have a Playstation 3, 2 and 1 built inside it, the Wii U needs a Wii, a Gamecube, an N64, SNES and NES (complete with cartridge slots), and Windows 8 should have XP, 98, 3.1 and DOS. That would increase costs to ridiculous levels (the PS3 is still too specific, complex and expensive to produce to believe it can be reduced to a cheap component inside the PS4), but it would also seriously hamper progress and innovation (so now the XBOX 1 needs to have an HD DVD drive to be compatible with the 360? What about the XBOX 2?)...
The other comments are pretty reasonable, but 3 is rather disingenuous... too focus in how consumers believe technology should work instead of how it actually works. I am sure Sony, Microsoft and Nintendo would love to have 100% BC, but they all know its not feasible.
