With more and more people taking advantage of the convenience ofdownloadable content, some might assume that this new trend will start to take away from traditional brick-and-mortar retail. Not so, says Microsoft UK 's Neil Thompson, as he toldMCVthat there is "growth of the download and digital content market – but it is complementary to boxed content and services." He doesn't see the packaged good business declining at all.

Think of it as the peanut butter on that PB&J sandwich. It's essential, yet complimentary at the same time. Anddelicious.

Sorry, DD fans, looks like you were wrong. :(

With that said, yay for blu-ray! :D
