Second only to the lackluster hardware improvements over the previous generation, the lack of backwards compatibility has been one of the most disappointing things about the current generation of consoles. Microsoft and Sony shut down any hopes of backwards compatibility down before the Xbox One and PlayStation 4 were even released, on the grounds that adding such a feature would be enormously difficult. That was two years ago, which is why nobody was expecting the big announcement that Microsoft made at its E3 press conference yesterday, the one where the company announced that the entire Xbox 360 would be coming to the Xbox One in the near future!
