The answer if a bit cynical is why make backwards compatibility when they can sell you the same game again? The PS4 is coming right out the gate with this with its $10 upgrade plan. Nintendo has more or less gotten a free pass on this with the virtual console (then again these games are not really feasible to Backwards compatiblize (this is now a word) but I'm willing to bet most of the guys shelling out money for Earthbound on the Wii U have a Super Nintendo Emulator somewhere with that and the rest of their childhood memories on it. Plus that old copy of Earthbound gathering dust with the old super nintendo in the closet/attic/garage/whereever)
The ps4 was the only console that actually needed to change their hardware in a way that removed backwards compatibility. The ps3's proprietary hardware was intentionally difficult to program for (their CEO's own words from just before when he became CEO) out of some silly fear that developers would conquer the system early on and bring the generation to an immature close. They should have been so lucky to have developers making games like Uncharted 3 and the Last of Us four years ago...
Because of the nature of that hardware, emulation would be nearly impossible on a technical and hardware level. It's not like the move between the ps2 to the ps3 in that regard. I think this was the best move. It'll ensure the easiest development process and ensure the maximum number of ports be made for the ps4 as the cost of porting has dropped off the face of the earth with that move. That $10 upgrade plan is if you own the ps3 version of a game that also comes out as a ps4 version. It has nothing to do with backwards compatibility and the $10 is likely to prevent some shenanigans with someone purchasing a preowned (aka, $0 profit transaction) game for $50 and then upgrading for free. $10 ensures they at least get something for a more advanced version of the game that the publisher actually invested in making.
Sony's BC solution is the Gaikai game streaming service. What's hilarious, is this could eventually even compete with Steam on some levels with the ability to play PS4 games on a tablet that's connected to a controller of some sort. But we'll see. I think Sony did the best they could in repairing the damage that the ps3 mistakes set up. The next generation is the only way to tell whether or not they'll fall to greed where non-BC is concerned. Because once you go x86, there's no excuse.
I'm still not sure why the XBO dropped it other than greed. The 360 was close enough to an x86 environment to where it should have been able to do this. But they made so many mistakes that it's hard to get any legitimate news on just one point.
Kudos to the WiiU. This was one of the few things they did right.
