Xbox 360 Emulation on Xbox One

Microsoft confirmed it's still working on plans to make Xbox 360 games playable on your Xbox One.This comes via development lead Frank Savage at Microsoft’s Build developer conference.
"There are still plans for an emulator but we’re not done thinking them through yet, unfortunately," said Savage. "It turns out to be hard to emulate the PowerPC stuff on the X86 stuff. So there’s nothing to announce, but I would love to see it myself."
